1. Calgary, Alberta, Canada – Langevin School Jump to Calgary’s Community Profile SELECTED FOR FLIGHT: Shells of Glass Capsules, Covered with Different Substances Reacting in Regular Water Grade 9, Langevin Science School, Calgary Board of Education Co-Principal Investigators: Metro Anderson, Safo Arthur, Arnav Jain, Tatum Parker Teacher Facilitator: Shane Turner Proposal Summary: The main aim of our project is to observe how three different capsule shells, covered in corn starch (Carbohydrates), gum Arabic (Gum) and sucrose (Carbohydrates) dissolve in regular water, in addition to the reaction and release rate in a microgravity environment. Our background research has stated that these substances will dissolve in water, but some may just settle at the bottom if let to sit for a certain amount of time. Certain coatings may react “faster” and ”slower” from lack of gravity but apart from that, we predict that starch will not be completely dissolved; gum Arabic will dissolve at all and sucrose will dissolve. The project will also consist of an acrylate, sodium polyacrylate. Sodium polyacrylate will stop the test sodium polyacrylate will absorb many times its size and form a polymeric gel. We are halting the dissolving process as we need to examine the results of the reaction of only sixty seconds. After the test is completed aboard the ISS, we will observe which substances can be completely dissolved, which can’t be dissolved at all or which were approaching their dissolving point. Once we have acquired this knowledge, future astronauts can be sent encapsulated medication with a certain substance covering the outer shell for more effective treatment. Knowing the differences may improve how a medication is produced and delivered into space. Medicine can also be improved on Earth by prolonging realise rate, and will make pills not needed as often. HONORABLE MENTION FINALISTS: Allergenic Proteins in Space – Where No One Can Hear You Wheeze! Grade 8, Langevin Science School, Calgary Board of Education Co-Principal Investigators: Benjamin Beaudry, Maxwell Couture Teacher Facilitator: Mr. de Jong
The group from Calgary dilutes hydrochloric acid to test the solubility level of gum Arabic.
Proposal Summary: Do you ever wonder whether allergies are worsened or lessened in space? The answer will be vital when long-term space travel becomes a reality. Allergies are caused by the immune system’s response to allergenic proteins. It is already known that microgravity changes multiple aspects of the immune system and yet there is no research regarding allergenic proteins in microgravity. Therefore NASA has no idea how allergenic proteins are affected is space. This leads to our specific question, “Will an allergenic protein change in microgravity?” A change within an allergenic protein could mean a change in the severity of an allergic reaction. Thus, our secondary question, “Will these structural changes alter the immune response?” It has been documented that microgravity can alter the function of the immune system, both during and after space flight. The immune system is key in causing allergy symptoms, it is unknown what effect microgravity can have on one’s allergenic symptoms. Some evidence already shows that proteins may be changed in space. The allergenic protein that will be tested upon will be Can f 1, this protein is responsible for 70% of dog allergies and it has a well-known crystal structure. How our experiment will be performed is simple, our group will send the Can f 1 protein into space and analyze it using circular dichroism to find any change between it and the allergenic protein currently on earth. These results will provide integral information in the field of allergenic response in space and on earth. The Effects of Vermicomposting in Microgravity Grades 8, Langevin Science School, Calgary Board of Education Co-Principal Investigators: Natalie Coulombe, Olivia Kelly Teacher Facilitator: Gemma Epp Proposal Summary: Can Eisenia fetida worms survive in microgravity and does microgravity affect the speed at which they compost? Our experiment involves compost and Eisenia fetida worms to see how the worms react to microgravity. Eisenia fetida worms are essential to accelerating the composting process on Earth. This experiment includes seeing if the Eisenia fetida worms will survive in microgravity with the added bonus of discovering if microgravity impacts the speed at which the Eisenia fetida worms compost. Conducting these two experiments in one will be more cost effective and efficient. This experiment is important because compost can be used for gardening and is a reusable alternative to garbage. If we are to one day live in space, we need to be able to compost efficiently. This experiment will be conducted in a confined space that is 170mm in length and 13 mm in diameter so a small Eisenia fetida worm will be used. The biodegradable materials that will be included in the experiment are manure, clovers, melons, maple leaves and soil. When our experiment is completed in space, we will compare it to the same experiment done on Earth to see if the When our experiment is completed in space, we will compare the results from the test done on earth and carefully analyze similarities and differences from the different tests. we will compare the rate the worm decomposes materials and if they’re more or less broken down compared to the test done on Earth.
2. Vancouver, British Columbia, Canada Jump to Vancouver’s Community Profile SELECTED FOR FLIGHT: Red Worm Composting In Microgravity Grade 6-7, Westcot Elementary School, West Vancouver School District 45 Co-Principal Investigators: Griffin Edward, Vesal Farahi, Shania Farbehi, Kristopher Kirkwood, Joseph Piovesan Advisors: Rick Adam, Dr. Leigh Palmer Teacher Facilitator: Matt Trask Proposal Summary: Our group proposes to send red worms into space with the aim of gaining important scientific knowledge that could lead to benefits for future space travel. On August 10, 2015, astronauts aboard the ISS harvested and ate romaine lettuce they planted in July. Red worms eat plants scraps and then excrete nutrients helping newer plants grow. This is called composting. As Patrick Cartwright said, there are many factors associated with composting: “Worms, however, are the real heroes of composting.” If we send our project into space, we will determine how red worms grow and function in microgravity. Astronauts lose their bone and muscle mass while in microgravity. Red worms have no bones but they do use muscles to burrow through dirt. We want to know whether or not red worms would be able to burrow in microgravity. Red worms are also a very important part of composting toilets. Composting toilets separates feces from other waste into a giant metal canister. Inside the canister, red worms then turn the waste into fertile soil that could be used to grow food. If red worms can grow in space, we could potentially have a fully functioning space garden with soil composted by the worms from the fecal waste produced by astronauts. Red worms in space would save the cost of transporting food into space because astronauts could grow their own food. As well, red worms could eliminate the cost of the waste capsules that are currently being used to dispose of human waste.
Vesal Farahi, Joseph Piovesan, Kris Kirkwood, Griffin Edwards and Shania Farbehi get ready to run more tests on worm cocoons to determine their optimal growing conditions.
HONORABLE MENTION FINALISTS: Seed Germination in Space Grade 7, Caulfeild Elementary School, West Vancouver School District 45 Co-Principal Investigators: Elissa Caetano, Clara Chalmers, Jennifer Gu, Marisa van der Horts Collaborators: Selena Brind-boronkay, Alex Caetano, Emma Shuparski Teacher Facilitator: Martin Andrews Proposal Summary: Our experiment incorporates the germination of a green-coloured plant, called Sweet peas. Its edibility is what convinces us that our highly- developed project should be the winning individual that receives a position upon Mission 9. We wish to become a minor influence over the development of plant growth in space, and we’re confident that our two seeds will germinate exceptionally in micro-gravity. This belief has sparked because of a chemical called Gibberellic acid (C19H22O6), which is stored in the left volume of our FME. The formula, when purified, will be expected to encourage plants to grow rapidly and extensively, with protection against frost. Our ambitions consist of quick seed germination, then preservation, and a helpful note for scientific research involving plant growth in microgravity. When investigating, it was found that our chemical may be the only essential our seed requires to germinate. Apparently, sunlight and the nutrients from soil are not a necessity in the first days or weeks our plants are growing in space. Astronauts, as we have gathered from research, aim for greenery to sprout and flourish away from their natural habitat on earth. This would improve astronaut’s diets up in space and also aid human settlement on Mars. Once our seeds have been germinated, another chemical, formaldehyde, that occupies the right volume of our tube, will be combined to the progressing experiment. Formaldehyde will preserve our seeds and will there-forth halt the growth, hopefully helping the wonders of space associated science. The Production of Synthetic Human Growth Hormone in Microgravity by Escherichia Coli Grade 7, Ecole Cedardale Elementary School, West Vancouver School District 45 Co-Principal Investigators: Avalon Bryan, Irma Barath, Mikaela Milic Teacher Facilitator: Kristina Hayes Proposal Summary: Currently, any individual who hopes to take part in a long-term spaceflight program will eventually experience physiological symptoms of prolonged exposure to microgravity that could negatively impact their performance-be it through their athletic performance or their cognitive ability. We hope to address this issue through genetic engineering. Through a simple recombinant process, we can successfully manufacture synthetic human growth hormone with the use of transgenic E. coli. This method has been used to successfully manufacture HGH in laboratories through the insertion of the gene into plasmids for over two decades. We aim to perform this procedure in a microgravity environment in order to form a definitive method through which HGH can be consistently synthesized in a microgravity environment. Our proposed experiment has the potential to provide a suitable way to stay in a microgravity environment for prolonged periods of time. If we succeed in manufacturing HGH consistently on the ISS, one would be less likely to succumb to such spaceflight induced symptoms as muscular and skeletal atrophy. One would consequently be capable of maintaining a healthy physiology without significant adverse effects. We will activate freeze-dried transgenic E. coli samples (with recombinant plasmids for HGH) using lysogeny broth. Ideally, the E. coli bacteria will transcribe the human growth hormone gene to supply synthetic HGH. Further production will be stunted using preventative antibiotics so that the bacteria remain stagnant during descent and later observation. Upon return to Earth, we will detect HGH production through blotting techniques.
3. Santa Monica, California Jump to Santa Monica’s Community Profile SELECTED FOR FLIGHT: The Effect of Microgravity on Preservation of Spam Using Lemon Juice Grade 8, Lincoln Middle School, Santa Monica Malibu Unified School District Co-Principal Investigators: Gina Kim, Thatcher Lee, Roxy Ong, Sydney Sobel Collaborator: Anthony Bvlgari Teacher Facilitators: Gretchen Gies-McLaunghlin and Carol Wrabel Proposal Summary: Considering the numerous restrictions, food storage has often been a predicament for space travel. The purpose of this experiment is to provide insight into more nutritious yet effective methods of food preservation. For this experiment, we will preserve a 7.5 cm x 0.8 cm x 0.8 cm block of “Classic Spam” with 4. mL of Lisbon lemon juice (citric acid). The question to be addressed is whether the preservation of spam in microgravity with citric acid, as measured by bacterial growth, differs compared to Earth. While the experiment is conducted aboard the International Space Station, the control experiment will be carried out on Earth. Once the FME returns from orbit, both samples will be compared to evaluate our hypothesis that in microgravity the growth of bacterial colonies will decrease (NASA). The goal of this experiment is to contribute ideas for food storage aboard the International Space Station. HONORABLE MENTION FINALISTS: What is the Effect of Microgravity on the Clotting of Sheep’s Blood when Mixed with Cornstarch and how do the Characteristics of this Clot Differ from the Sheep’s Blood Clot made on Earth? Grade 8, Lincoln Middle School, Santa Monica Malibu Unified School District Co-Principal Investigators: Weston MacWilliams, Savannah Yassin Co-Investigators: Emily Chase, Makenna Gaeta, Owen Halpert Teacher Facilitators: Verian Wilson and Marianna O’Brien
Student scientists preparing a sample for the FME.
Proposal Summary: Sheep’s blood is the closest type of blood available to send in the FME to human blood. The proteins in sheep’s blood are very similar to those in human blood. Thus, we would like to propose an experiment on the clotting of sheep’s blood in microgravity. This experiment will test if sheep’s blood will clot the same way in microgravity as it does on Earth, using cornstarch as the clotting initiator. Cornstarch will trigger the coagulation cascade, serving as the irritant to commence the series of zymogen activations that causes coagulation. (Stryer) The materials we are using in our proposed experiment are defibrinated sheep’s blood and Argo Cornstarch. We are using a Type 2 FME with the sheep’s blood in the main FME volume and the cornstarch in the other volume. When combined, the cornstarch and sheep’s blood will mix and the cornstarch will act as the catalyst to initiate coagulation. When the FME returns to Earth, we will compare the clot made on Earth to the one made in microgravity to determine if blood clots the same way in microgravity as it does in Earth’s gravity, and if the viscosity, molecular structure, color, and physical features are the same in the two samples. We hypothesize that sheep’s blood will clot in microgravity the same as it does on Earth. The results of this experiment will be recorded and used to help scientists have a better understanding of blood clotting in microgravity. The Effect of Microgravity on the Deterioration of Contact Lenses Grade 8, Lincoln Middle School, Santa Monica Malibu Unified School District Co-Principal Investigators: Aidan Blain, Daisy Billington, Chloe Forssell, Emma Guerrini Romano, Colin Wu Teacher Facilitators: Gretchen Gies-McLaughlin and Carol Wrabel Proposal Summary: In our experiment, we aim to examine differences that may occur during the deterioration process of a contact lens in microgravity and a contact len on Earth. Our team will gain valuable knowledge about the dangers of wearing contact lenses in microgravity and the long term effects it can have on an astronaut’s eye and overall vision. In our experiment, we will be working with a Type 1 FME. In the volume, we are filling the space with 9 mL of saline solution, and then continuing to insert 7 Acuvue soflens contacts to float in the solution. We will use 7 contacts because the more test samples we have, the more tests we get to run, allowing us to gather more critical data for our final analysis. When our experiment comes back to Earth, we plan on taking the contacts to a lab, where we can then undergo any further tests that we wouldn’t have been able to find on our own. A few of the tests that we plan on running are as followed: Gas Chromatography, Refractive Index, and Tensile Stress, along with collecting data from visual qualities and simple measurements at our school. With the knowledge that we will receive, we can learn if it is safe to wear contacts in space or not. Additionally, allowing astronauts to wear contacts in space will lead to an easier and more efficient lifestyle aboard the International Space Station.
4. East Lyme, Connecticut Jump to East Lyme’s Community Profile SELECTED FOR FLIGHT: Will a Biofilm Form on a Rat Catheter in Microgravity Differently than in Gravity? Grade 6, East Lyme Middle School, East Lyme School District Co-Principal Investigators: Ritisha Ande, Madeline Fraser, Ethan Moore, Ethan Novick Teacher Facilitator: Deborah Galasso Proposal Summary: The purpose of this experiment is to see if a biofilm will form differently on a rat artery catheter in microgravity from the bacteria Staphylococcus epidermidis, which is naturally occurring in the human body. If the biofilm forms thinner in space than on Earth, this will provide added information to NASA for astronaut health and information for scientists and doctors to hopefully improve catheters and reduce infection on earth. We already know that Staphylococcus epidermidis is a bacterium that is already in the human body for all people. When someone has a catheter in their body, a Staphylococcus epidermidis biofilm can form on it causing this skin infection. The skin disease is an acne-like rash that is red and inflamed. If a person has surgery, he or she is more likely to get a biofilm on their catheter. This happens because Staphylococcus epidermidis likes to stick to any type of plastic. After it sticks it can create a biofilm that clogs the catheter or the implant. This leads to failure and infection (Cuong and Otto 1). We would like our experiment to be running for 2 days on the space station in order for the bacteria to multiply sufficiently. We chose this experiment because many people have died from having this condition known as a Staph infection. This experiment can help because if an astronaut gets sick on the ISS and needs a catheter inserted, we will know better the risks that are involved with this procedure.

HONORABLE MENTION FINALISTS: Rust Growth on Steel and Iron Grade 5, East Lyme Middle School, East Lyme School District Co-Principal Investigators: Julia Locklear, Ava Pitruzzello, Katrina Shevchenko, Kaylyn Wojcik Teacher Facilitator: Carla Woitovich Proposal Summary: For our experiment the question we will address is will rust form on steel and iron in space? Our hypothesis is that the rust will grow slower and less on both the steel and iron metals. We think that in microgravity the chemical process of rusting will be affected. We think the presence of microgravity could slow down the process. We only used four materials: steel, iron, baking soda, and water. We are going to perform the experiment by exposing 4.5 ml of water to the two metals. We will do this because when certain types of metals are exposed to water and oxygen over a long period of time, it forms rust. On the fifth week, we will mix half a teaspoon of baking soda with the water and stop the rusting process. The baking soda will do this because it creates a chemical reaction with the water that interrupts the rust’s growth. This is important because an organization called Mars 1 Foundation is trying to start a civilization on Mars. If rust forms on the buildings we will need to know how to stop the rusting process. We are using steel and iron because they are some of the most common building materials and are known to rust on earth. Iron and steel can be used to make building structures and tools. We will observe the results by measuring the mass of the metals before and after they are exposed to the water and with visual observations. Hydra Physical Changes and New Functions in Microgravity Grade 6, East Lyme Middle School, East Lyme School District Co-Principal Investigators: Oliva Goldreich, Julia Smith Collaborators: Lucas Lewis, Katie Mullins, Kate Pierce Teacher Facilitator: Linda Nastri Proposal Summary: Our group is studying the hydra, which is a Genus creature. It is a microscopic organism that lives in freshwater. It can have 7-25 tentacles and its mouth on one side of its slender tube like body, (1\2 – 1\4 in.) and a sticky part on the other side that attaches to where it is staying, which is called the foot. This is just an experiment to see what might happen when the hydra is sent into space to try and live. But because of its regenerative ability, it might be able to live in the microgravity. We also want to put its prey in with it to see if it might last longer with food. The Hydra prefers to eat Water Fleas, Daphnia, and almost anything smaller than itself. In this experiment though, we are using water fleas. We want to know if Hydra can catch its prey in microgravity. So maybe the way it lives in freshwater might affect its body when it is put in the 10% Neutral Buffer and the 10% Formalin Fixative. Maybe it will change to adapt in microgravity (Because of its regeneration) so microgravity might neutralize the effect of when it is stinging its prey with its nematocysts. This is just an experiment for science, so who knows what will happen!
5. Hillsborough County, Florida Jump to Hillsborough County’s Community Profile SELECTED FOR FLIGHT: Germination of Quinoa in Space Grade 5, Mabry Elementary School, Hillsborough County School District Co-Principal Investigators: Jessie Babb, Serena Bassart, Mya Metheny, Julianna Tran Teacher Facilitator: Jessica Strauss Proposal Summary: Our group proposes to investigate how microgravity affects the germination of quinoa seeds. We are planning to count the seeds germinating on Earth compared to the seeds that germinate in microgravity with the same investigation. First we will set up the test tube with one clamp separating the murshinge (gel to hold seeds) and the seeds. We would tell the astronauts on board to unclip the clamp and then shake the tube gently (shake from side to side) until the seeds are stuck within the gel. We will count the number of seeds and how they formed in both microgravity and Earth. HONORABLE MENTION FINALISTS: Chromatography in Space Grade 5, Hunter’s Green Elementary School, Hillsborough County School District Principal Investigator: Caden Long Co-Investigators: Ethan Stinnett, Shane Win Teacher Facilitator: Cheryl Pahl

Proposal Summary: We are doing paper chromatography. We are doing this because we want to see if water can move ink in space and if microgravity affects how the chemicals in the ink separate on the paper. The purpose is to see if microgravity affects how ink and chemicals separate in space. Rust, or Not? Grade 5, Hunter’s Green Elementary School, Hillsborough County School District Principal Investigator: Bilal Abouzied Co-Investigators: Sami Al-Jamal, Chance Young Teacher Facilitator: Cheryl Pahl Proposal Summary: We are doing an experiment on if metal can rust in space. We are putting iron filings on one side of the tube and tap water on the other side of the tube. Then we will put a clamp in the middle and then take the clamp and shake the tube for five seconds. Then observe if the iron filings rusted. We are doing this experiment because if some water gets on the metal spaceship our experiment will tell if the metal spaceship will rust or not.
6. Boise, Idaho Jump to Boise’s Community Profile SELECTED FOR FLIGHT: Living Water Filters: Triops in Microgravity Grade 5, North Star Charter School, North Star Charter School District Co-Principal Investigators: Alexandra Garvin, Bailey Corrigan, Bostyn Corrigan, Raigan Teeter Co-Investigators: Madeline Clark, Azzio Simontacchi Teacher Facilitator: Patrice Rex Proposal Summary: Scientists have wanted to send people to other planets for a long time. We’ll need pipes and plumbing, but what will clean the waste-water produced by people living in space? Triops could possibly be used in microgravity because they eat organisms like bacteria, algae, mosquito larvae and water fleas that can make the water unsafe for drinking. Triops are small crustaceans that have been on Earth since prehistoric times. They are filter feeders that can remove harmful organisms from water sources. Our experiment will test if test if triops can filter bacteria out of pond water in microgravity as well as they do on Earth. After the experiment is returned to us, we will work the Boise Waste Water Treatment facility to analyze the water to see which kinds of bacteria remain in the water, using a Heterotrophic Plate Count method. We will also measure the mass of the triops that were hatched in microgravity and compare it to the mass of the triops that were hatched on Earth. Water is essential to life; it must be clean for drinking. If it is not clean, it can do harm to the person or animal consuming the water. If triops could function properly in space, astronauts could release triops into the water source to clean it.

Proposal Summary: Mars, will there ever be life there? Cyanobacteria is a natural choice as a resource for improving soil for other plants to grow because of its ability to take nitrogen out of the atmosphere and convert it into ammonia and nitrate in the soil. In addition, cyanobacteria are better solar collectors than plants, they are edible and provide most vitamins and minerals needed to sustain a healthy diet, they improve the oxygen levels in the atmosphere, and they can be used to produce fuel making them a great resource of space travel (Stone, 2015). Most cyanobacteria use photosynthesis to produce sugars that they require to grow, however, some cyanobacteria are able to use a secondary pathway to access sugars from their environment when it is dark. Do to the limitations of the FME mini-lab we will be using Anabaena sp. strain PCC 7120 which is able to grow in the dark using fructose from its environment (Stebegg, Wurzinger, Mikulic, & Schmetterer, 2012). Additionally, Anabaena sp. strain PCC 7120 has been successfully grown on Mars soil simulant within a 1G environment (Verseux, de Vera,Lehto, & Rothschild, 2015). Wamelick et. al. (2014) identified the need for research into how gravity influences the growth of organisms in Mars soil. The reason for our experiment is to discover how well Anabaena PCC 7120 is able to grow on and to cause nitrification of Mars soil in microgravity. We will be using a Type 3 FME mini-lab to implement this experiment. Epigentetic Changes in Caenorhabditis Elegans as a Result of Microgravity Grades 7 and 11, North Star Charter School, North Start Charter School District Co-Principal Investigators: Kaden Baxter, Connor Betz, Gabe Evans, Josie Lipps, Darin Neuberger Co-Investigators: Roxy Boucher, Julia Galenko, Cassidy Puatu, Kylie Smith, Jessica Stelzner Advisor: Jon Pierce-Shimomura Teacher Facilitator: Jill Hettinger Proposal Summary: Caenorhabditis elegans (C. elegans) are a small roundworm about 1mm long. They have been used in multiple experiments that have been conducted on the ISS, including a SSEP experiment during mission 3 that was interested in seeing if C. elegans would survive the microgravity environment (SSEP, 2012). It is now well understood that C. elegans will survive in microgravity (Higashitani, 2015). Our experiment seeks to discover if the environmental stress of microgravity will cause changes in the epigenetics of C. elegans. Specifically, we will compare the epigentic effect of microgravity on muscular dystrophy worms that already express atrophy in their muscles and healthy wild-type N2 worms. We chose to work with C. elegans because they have been used successfully in microgravity. We will be using a Type 2 FME minilab that will contain a two small population of C. elegans N2 wild-time and C. elegans dys-1 mutant worms in E.coli enriched agar. The dys-1 mutant worms have been genetically manipulated to be green in color, and the two worm types will not cross-breed. We expect our C. elegans samples to go through a minimum of three generations while on the International Space Station.
7. Potomac, Maryland Jump to Potomac’s Community Profile SELECTED FOR FLIGHT: Shewanella oneidensis and Iron Ions in Microgravity Grade 10, Bullis School Co-Principal Investigators: Skylar Jordan, Amanda Kay Advisor: Dr. John Ondov Teacher Facilitator: Daniel TerBush Proposal Summary: We expect that the process by which Shewanella oneidensis removes metal ions from water will not differ in microgravity compared to normal gravity. Water is a necessity for human life and everyday, many metals are found in important water sources. Many people do not realize how the water they are consuming are contaminated with heavy metals. Excess amounts of heavy metals can destroy vital human organs such as the brain and liver. This experiment tests how Shewanella oneidensis can remove heavy metals from contaminated water which will help future water contamination issues if the results come back as expected. First, data will be collected based on the amount of iron ions present in the water before coming in contact with Shewanella oneidensis. This will be collected before sent to the International Space Station (ISS). Data will also be gathered for the amount of iron ions in the water after coming in contact with the bacteria. This data will be collected after the experiment comes back from the ISS. Since the hypothesis states that gravity will not effect the removal process, the amount of iron ions present in the microgravity experiment are expected to be the same as the amount present in the ground experiment. When both experiments are back in the lab, we will compare the amount of iron ions in the solutions to tell if Shewanella oneidensis removed iron ions differently in the two different environments and whether or not gravity affects the removal process of iron ions.
Bullis School students Skylar Jordan and Amanda Kay prepare their FME mini-lab for flight to the ISS.
HONORABLE MENTION FINALISTS: Growth of Aloe Vera in Space Grade 8, Bullis School Co-Principal Investigators: Marianna Anagnostou, Joey Chmara, Danielle Dyer, Olivia Kazanjian Teacher Facilitator: Chelsea Henry Proposal Summary: The proposed question is, what is the effect of microgravity on the germination of an Aloe Vera seed? Aloe Vera has a variety of uses in the medical and cosmetic fields that make it a very important contribution to these industries. Additionally, Aloe Vera is used to aid in treating a variety of sicknesses and diseases such as constipation, hemorrhoids, asthma, colds, bleeding, colitis, depression, diabetes, multiple sclerosis, and epilepsy. We will prepare an FME containing two Aloe Vera seeds, cactus soil, and water. One to be conducted on earth, and one to be conducted in space. If we determine that Aloe Vera seeds germinate better in space, then this could mean that more Aloe Vera can be grown at the ISS and will make for more derivatives from the plant to be used for medical and cosmetic purposes. This experiment will help us answer the proposed question of regarding the germination of Aloe Vera seeds in space. The Effect of Microgravity on the Birth Rates and Early Development of Nothobranchius Rachovii Grade 10, Bullis School Co-Principal Investigators: William Evans, Liam Vinal Teacher Facilitator: Daniel TerBush Proposal Summary: The hypothesis of the experiment is that less fish will be born in the microgravity environment because their bones and muscles will not be able to develop as quickly and the unnatural microgravity environment will cause less fish to hatch. The experiment will test birth rates to see how complex organisms develop in space from an early age. The hypothesis will be tested to see if organisms will be able to develop in space. Fish eggs will be sent into space in the tube, and the same amount of fish eggs in the same tube will be kept at home. We will hatch the eggs in space, as well as back on earth, and after two days euthanize and preserve them. The birth rates will tell us how microgravity affects their development. The expected results are that fewer eggs will hatch in space than back home. The birth rates will tell us if complex organisms, such as humans, would be able to develop from an egg state in space.
8. Fitchburg, Massachusetts Jump to Fitchburg’s Community Profile SELECTED FOR FLIGHT: Streptococcus mutans Production of Lactic Acid in Microgravity Grades 10-11, Montachusett Regional Vocational Technical High School, Montachusett Regional Vocational Technical School District Co-Principal Investigators: Olivia Houle, Shelby Landress Collaborators: Madison Clark, Zachary Houle Teacher Facilitator: Paula deDiego Proposal Summary: This experiment has the potential to be successful in finding a more efficient dental care regimen for astronauts. The factor to be observed in the experiment is whether or not Streptococcus mutans produce more lactic acid in microgravity and if the reproduction rate of the previously stated bacteria is affected in space. Improper oral hygiene is a factor that contributes to poor health in the rest of the body. If the Streptococcus mutans prove to be a greater force in space than they do on Earth, then the aseptic habits of astronauts may need to be modified. Previous studies referenced in this proposal reinforce the hypothesis that dental caries are more likely to occur in space because of how microgravity influences S. mutans. HONORABLE MENTION FINALISTS: The Resistance of Fluconazole on Candida dubliniensis in Microgravity Grade 10, Montachusett Regional Vocational Technical High School, Montachusett Regional Vocational Technical School District Co-Principal Investigators: Abbigayle McIntosh, Abigail Clark Teacher Facilitator: Paula deDiego Proposal Summary: Our whole project revolves around if Candida dubliniensis is more resistant or less resistant to the anti-fungal drug Fluconazole in microgravity. Candida dubliniensis is a fungus that is commonly found in HIV patients, or someone who is immunocompromised, but in rare cases can be found in healthy patients. Candida dubliniensis causes yeast infections, in HIV patients the fungus usually presents itself in the oral cavities, but also can be found in fecal matter, urine, can cause oropharyngeal, and vaginal and bloodstream infections. Researchers had figured out that the fungus’ ATP keeps the CDR 1 and CDR 2 activated, thereby leads to the fungus’ resistance to the anti-fungal drug fluconazole. We would like to find out is if the production of ATP slows down, would the CDR 1 and CDR 2 in the cells genes become inactivated and make Candida dubliniensis susceptible to the drug fluconazole.

Bifidobacterium longum in microgravity Grades 10-11, Montachusett Regional Vocational Technical High School, Montachusett Regional Vocational Technical School District Co-Principal Investigators: Alexis Arsenault, Jessie Cote, Kristyn Gordon, Grace Kirrane Teacher Facilitator: Paula deDiego Proposal Summary: Our experiment consists of testing the growth of Bifidobacterium longum in microgravity. Through this experiment we will discover whether or not the product of the bacteria is greater or has decreased when in microgravity. In space, astronauts immune systems tend to weaken due to less cell activity. As cell activity decreases, the body’s immunity weakens. Their risk of illness and infections is higher. Here on earth Bifidobacterium longum helps citizens to maintain good digestion, boost the immune system, and produce lactic and acetic acid that control intestinal pH.

Traverse City, Michigan Jump to Traverse City’s Community Profile SELECTED FOR FLIGHT: Growth of Blue-Green Algae in Space Grade 10, Traverse City West Senior High School, Traverse City West High School Co-Principal Investigators: Sam Church, Ryan Hayes, Hayden Holmes, Robert Lohr Teacher Facilitator: Patrick Gillespie Proposal Summary: We are testing the growth of Blue-Green algae to see if the growth changes when it is put in space, We want test this because the blue-green algae produces hydrogen and oxygen, so that later in the future when we’re in space we can use the oxygen to breathe and the hydrogen as fuel. We will be putting the algae in the capsule with water, a rock, and plant fertilizer for nutrients. We will have the same rocks, amount of water, and amount of algae here on earth. HONORABLE MENTION FINALISTS: Difference in Oil Absorbency Between Gravity and Microgravity Grade 10, Traverse City West Senior High School, Traverse City Area Public Schools Co-Principal Investigators: Lauren Camp, Joel Cerny, River Leachman, Alexis Zoutendam Teacher Facilitator: Patrick Gillespie Proposal Summary: We propose to combine 3 ingredients, (3.5 ml of water, 3.5 ml of oil, and a feather) to see if gravity on earth compared to no gravity in space will effect how much oil gets absorbed in the feather. This idea was inspired to us by thinking that oil and water can mix in space rather than on earth. They won’t mix because of gravity, it’s just layers with oil being the top layer and water the bottom layer. As a group we believe that in space the feather will absorb more oil because it’s mixed into the water better. We tested on earth the oil absorption of a feather to be able to compare to the feather going to space. The feather gained 0.0835g of oil. We will use this data to see whether absorption in space is greater. On earth with the gravitational force oil layers on top of water so it would absorb less water having only the oil on top to absorb into the top of the feather. This experiment would benefit resource transportation in space because we would know the extent of how oil and water mixes in space when transporting oil and water in an oxygenated environment. Resource distribution could troubleshoot oil and water spills in space better with an understanding of how oil and water mix in space. When transporting resources to inhabit planets such as Mars, we will need to know how oil and water mix in zero-gravity.

Cell Growth in Microgravity Grade 10, Traverse City West Senior High School, Traverse City Area Public Schools Co-Principal Investigators: Ashley, Caughell, Anna Jarvis, Ana Walters Teacher Facilitator: Patrick Gillespie Proposal Summary: Our proposal is cell growth in microgravity, specifically the ‘immortal’ cell line of Henrietta Lacks’s cervical cancer. We will be using a Type 2 FME tube for our experiment. Volume one will contain the HeLa cells and volume 2 will contain the growth medium RPMI 1640. The idea and hope is that the cells with the growth medium will have significantly different growth results than same experiment on earth. By running this experiment we can see the effects of microgravity on the growth and reproduction of human cells. We plan to have the astronauts unclamp the tube on day 1 and vigorously shake for 30 seconds in order to expose the cells to the medium as soon as possible . After that, we plan for there to be no interactions until day 4, which will consist of 10 seconds of gentle shaking. When our experiment returns, we will document the appearance, mass, and any change in the shapes of the cells after growing in microgravity.

Jersey City, New Jersey Jump to Jersey City’s Community Profile SELECTED FOR FLIGHT: The Effects of Microgravity on Muscle Tissue Regeneration Grade 12, McNair Academic High School, Jersey City Public Schools Co-Principal Investigators: Joshua Monserate, Jay Pandya, Nirav Patel, Sardar Hamza Zakria Teacher Facilitator: Maria Emma Osoria Proposal Summary: The aim of the experiment is to analyze the potential of the drug, Tissue Regeneration Factor at 150 mg (TRF-150) to regenerate shoulder muscle tissue of an adolescent pig faster when exposed to a microgravity environment. Therefore, the analysis aforementioned will determine the amount of tissue regenerated under controlled scenarios of induced harm. Both qualitative and quantitative methods of measurement will be used to determine this experiment’s success. Quantitative measurements include density of the remaining tissue and amount of oxygen and glucose consumed. Qualitative analysis will include placing the tissue under a scanning electron microscope to visually determine how much of the tissue has regenerated and the pattern of the issue regenerated. This experiment will be conducted in a Fluids Mixing Enclosure (FME) Mini-lab type 3 with a solution of formaldehyde and TRF-150 at the edges of the tube, in the middle of the tube will be the tissue in question with a controlled incision made on it and a solution of glucose, proteins, oxygen and testosterone. This experiment will help determine if a microgravity environment aids in the regeneration of organic tissue. If the experiment implies the increase of the regenerative properties of TRF-150 then simulated microgravity environment can be implemented to help patients enduring a muscle injury.

HONORABLE MENTION FINALISTS: Does Microgravity Affect the Sex Ratio of Fruit Flies (Drosophila melanogaster) in a Microgravity Environment? Grade 5, Public School 27, Jersey City Public Schools Co-Principal Investigators: Arhaan Misra, Kevon Owusu, Joshua Torres, Johann Varghese Teacher Facilitator: R. Ernesto Burgos Proposal Summary: Our experiment is to explore if microgravity affects the sex ratio of fruit flies wild Drosophila melanogaster during development in microgravity compared to their development on Earth. The fruit fly’s sex is determined during the pupae stage of its life cycle. Both fruit flies and humans have X and Y chromosomes but fruit flies only have 8 chromosomes compared to the 46 that humans have. Unlike humans, the Y chromosome doesn’t determine the fruit fly’s sex but instead helps make genes for a male fruit fly to reproduce. The fruit fly’s sex is determined by the ratio of its X chromosomes to its autosomes. Each cell decides whether the fruit fly should be a male or female that sometimes produces gynandromorphs (having both male and female body parts). Scientists can further test to see how these potential changes will affect the ecosystems in the biospheric environment on the moon or Mars, where there is much less gravity than on Earth. Microscopes will be used to determine the sex ratio of males to females produced in microgravity. We hypothesize that the sex ratio will be favorable to females. Thus more female fruit flies will survive in microgravity, because previous experiments show that exposed fruit flies to sudden changes in temperature using an incubator has shown that female fruit flies can withstand harsh changes in their environment better than males. Since female fruit flies carry hundreds of eggs after mating, their bodies can withstand harsher changes to their environment. Effects of Microgravity on Neuronal Morphology Grade 12, McNair Academic High School, Jersey City Public Schools Co-Principal Investigators: Serena Tang, Raefah Wahid Co-Investigators: Kush Baldha, Nikunj Jhaveri, Miraj Patel Teacher Facilitator: Maria Emma Osoria Proposal Summary: In this experiment, analyses about the morphological changes that are experienced in neuronal cells’ synapses in microgravity will be conducted. Data about neurons from a microgravity environment will be compared with those in Earth’s gravitational environment in order to qualitatively and quantitatively form conjectures about the changes in the mental abilities of astronauts (such as memory performance, information recollection, etc.). The experiment will be conducted using hippocampal neurons from a rat’s brain, a Neurobasal medium, and a culture kit from BrainBits. The neurons will be transfected with the hChR2 gene, which will allow the cells to express a light sensitive protein called channelrhodopsin-2. These proteins will allow the neurons to fire only in the presence of blue light (~470 nm). The tube will be covered on the inside by a phosphorescent blue film, which will allow blue light to enter the tube in the dark after being charged by ambient light. The neurons will be kept in a dark environment and surrounded by cold packs until the tube reaches the International Space Station (ISS). After approximately three days on the ISS, a fixative of 6.5% paraformaldehyde in phosphate-buffered saline (PBS) will be released to preserve the culture until it is brought back to Earth for analysis. When the culture reaches Earth, a Transmission Electron Microscope (TEM) will be used to conduct synaptic analyses and form conjectures.
11. Springfield, New Jersey Jump to Springfield’s Community Profile SELECTED FOR FLIGHT: The Effects of Microgravity On Grass Seeds’ Growth Grade 7, Florence M. Gaudineer Middle School, Springfield Public Schools Co-Principal Investigators: David Ares III, Jeremy Dash, Daniel Munoz Co-Investigators: Timothy Burns, Antonio Nacci Teacher Facilitator: Alison Gillen Proposal Summary: We are interested in seeing if microgravity affects the growth rate of plant seeds. In our experiment we want to test the effects of microgravity on the growth of Rye grass seeds. Our group is also testing to see if Rye grass seeds are able to grow without gravity and light. We have found conflicting information during our research. We have been taught in school, through books that gravity affects the way seeds are grown. The roots grow in the direction of gravity. However, in the articles we read online, it was written that gravity had little affect on the way seeds were grown. We think the benefit of trying to grow seeds in microgravity is: if people needed to stay in space for long periods of time, they need to know the total effects of microgravity on plant growth. We think that the seeds will grow in microgravity and their growth will increase more than on Earth. For our experiment to start the seeds’ growth, we will only give our seeds water. In our three-chambered tube we will put water in volume 1, Rye grass seeds in cotton to keep them in place in volume 2, and in volume 3, we will have salt for our fixative. Because of the tests we have done we know that on average a Rye grass seed take 5-12 days to grow. And we have been able to stop the growth using a salt solution.

Grade 7 student researchers experimenting with optimal germination conditions for studying the effects of microgravity on the growth of grass seeds.
Proposal Summary: We are interested in the rates of growth of brine shrimp, if they grow faster or slower in microgravity. Brine shrimp are small organisms that take around 8 days to become an adult. Microgravity is a fantastic environment to explore the potential of brine shrimps growth rate changes! This information could help future exploration by showing if it is safe to grow organisms in space. This research could help to find out information for the unknown affects of microgravity. We anticipate that the results of the growth rate of brine shrimp will increase, since microgravity contains near weightlessness conditions. For our experiment, the brine shrimp will be given salt water to start their development. After nine days, the chamber will be flooded with a growth inhibitor. This will allow us to stop their growth. Once the brine shrimp have returned to Earth, we can compare abnormal growth, accelerated growth, or any other differences. The Breakdown of Penicillin with Beta Lactamase in Microgravity Grades 10-11, Jonathan Dayton High School, Springfield Public Schools Co-Principal Investigators: Carly Gartenberg, Alexandria Giordano, Ashley Korieocha, Jessica Lagemann Teacher Facilitator: Jennifer Greenspan Proposal Summary: Penicillin, which is often described as a “miracle drug”, is a vital antibiotic that fights infections that interfere with the cell wall of bacteria. One problem that scientists and doctors face with this drug is that bacteria are forever changing to develop immunity to penicillin. If given the opportunity to send an experiment into space with the Student Spaceflight Experiments Program, our group would like to investigate the effect of microgravity on the breakdown of penicillin by beta lactamase, an enzyme that breaks down penicillin. To complete this experiment, we will use liquid forms of penicillin and beta lactamase and ask astronauts to mix the two by shaking them gently. This will allow the two liquids to interact, ultimately causing the breakdown of the penicillin. Then, we will preserve the structure of the broken down penicillin with Formalin FBF and observe it on Earth using mass spectrometry. Our experiment might prompt future scientists to investigate infections that can be found in space and their resistance to penicillin. This could help any future space travellers and the future generations that could eventually live in space.

Buffalo-Niagara, New York Jump to Buffalo-Niagara’s Community Profile SELECTED FOR FLIGHT: Tuber Transport and Subsequent Terrestrial Growth Grades 7-8, Hamlin Park Claude and Ouida Clapp School #74, Buffalo Public Schools Principal Investigator: Gabriella Melendez Co-Investigators: Toriana Cornwell, Shaniylah Welch Advisors: Dr. James Berry, Dr. Mary Bisson, Cornell Agricultural and Life Sciences Department Teacher Facilitator: Andrew Franz Proposal Summary: This project is about the germination of Yukon gold potatoes because of the distinct lack of grocery stores in outer space. Plants on earth develop under the influence of gravity. Plants must support themselves against the force due to gravity. On the International Space Station, a vehicle that is in constant free fall, gravity does not hold the same effect (microgravity). We believe that germination in small containers is necessary to eventual planetary terraforming (you can start the growth process before landing on another planet). We wish to try to grow potatoes on the International Space Station so we can see if the plants will be able to grow on other planets, or travel there. HONORABLE MENTION FINALISTS: The Effect of a Microgravity Environment on the Rate of Breast Cancer Cell Growth Grades 10-11, Global Concepts Charter High School, Global Concepts Charter High School Co-Principal Investigators: Zaina Alsadam, Kendall Cerrone Advisor: Dr. Adam Kisailus Teacher Facilitator: Rebecca Poremba

Proposal Summary: About 1 in 8 U.S. women will develop invasive breast cancer over the course of her lifetime. Breast cancer cells migrate in an unregulated fashion called metastasis. Here on Earth, metastasis is controlled by gravity. Our experiment involves sending live breast cancer cells to the International Space Station to see the rate at which breast cancer cells grow in a microgravity situation. The results of this experiment will determine the effect of gravity conditions on breast cancer tumorigenecity. Measuring the rate of metastasis in a controlled microgravity environment on this small scale could also allow scientists the ability to see what would occur if they changed the dynamics of the environment in which the cancer cells are growing, gaining insight into experimental microgravity therapies for cancer. The Battle of Antibiotics vs. Bacteria in Microgravity Grade 5, Harry F. Abate Elementary School, Niagara Falls City School District Co-Principal Investigators: Louis Lodovico, Michelina Renda, Genesis Sanders, Parker Urban Advisor: Dr. Mark Gallo Teacher Facilitator: Ronni McGrath Proposal Summary: For our microgravity experiment, we will investigate if antibiotics still work to kill bacterium in microgravity. Our purpose is to give aid to the astronauts if they are ill. In our research, we are using E.coli, but in microgravity experiment and our ground truth experiment we will use bacterium grown by yogurt because it is a lot safer. We don’t want to make the astronauts sick. We will send liquid antibiotics and dormant bacterium in the FME. The bacterium is affected when it is exposed to the liquid antibiotics. We have learned that astronauts have lowered immune functions while in microgravity so this research is important. Our hypothesis is that if we put antibiotics in a test tube with the bacterium, it will still kill the bacterium because the chemicals in the antibiotics will reach the bacterium no matter what.
13. Eugene, Oregon Jump to Eugene’s Community Profile SELECTED FOR FLIGHT: SLIPS in Microgravity Grade 8, Arts and Technology Academy, Eugene School District 4J Co-Principal Investigators: Ray Newell, Garrett Price, Kobe Skidmore Teacher Facilitator: Kathleen Taylor Proposal Summary: Does Slippery Liquid-Infused Porous Surfaces (SLIPS) decrease the scale of an omniphobic surface in microgravity? An Omniphobic Surface scale is a measurement of how slippery something is. SLIPS is the world’s slipperiest substance, it has been out for half a year, and is based off the functionality of the pitcher plant. After it rains pitcher plants keep raindrops as a film on the edge of their mouth so that when ants walk on the rim, they slip into their stomach. SLIPS only does one thing, it makes a surface of a solid slippery so that no liquid can touch the face of the solid that’s coated. We are testing SLIPS in a microgravity environment to find out if it has the same properties as it does on Earth. If it does it could possibly solve frostover for rockets at launch and in microgravity. We will be using a type 3 FME. Inside volume 1 we will have a cotton ball. Inside Volume 2, there is an aluminum strip 12.5mm x 35mm coated with SLIPS on one side. In volume 3 there will be 1.5ml of corn syrup. The tube will be coated on the inside with SLIPS in both volume 2 and 3. In this experiment we are hoping to solve frostover on the ISS with SLIPS by finding if SLIPS can not only stay on the face of a solid but still make liquids slip off of the solid.

If they work then that will mean that we can send the seeds into space so that astronauts can have a large source full of protein, fiber, calcium, and other vitamins and nutrients all in one plant. Salvica Hispanica is a great and healthy food that can be put into many different meals and can be prepared many different ways. Sea Monkey Astronauts-The Life Cycle of Artemia nyos in Microgravity Grades 11-12, Churchill High School, Eugene School District 4J Co-Principal Investigators: Alexander Cordova, Aileen Hernandez, Gabe Peterson-DeGroff, Beau Scott, Brycen Spencer, Sierra Squires Teacher Facilitator: Evan Munger Proposal Summary: Our group decided to focus our experiment around the topic of marine life in space. Brine Shrimp, which are a very sturdy animal that does not need any special accommodations, will be the subject of our experiment. On Earth everything is effected by gravity one way or another. Organisms have muscles in their body to lift and push themselves away from Earth’s gravitational pull. Aquatic life is no different. Organisms have muscles to push on the water around them in order to not sink from gravity trying to pull it down. Our experiment is intended to take that variable, gravity, and decrease its strength and record the effects. Since we are not able to send a camera, or other electronics, up to the ISS to watch every move, we plan on recording the data in a few other ways. One of which will be food consumption. We can hold a control down on Earth and track the difference in the amount of food that is consumed. By that we can make assumption as to which group of shrimp are burning more energy.
14. Columbia, South Carolina Jump to Columbia’s Community Profile SELECTED FOR FLIGHT: The Effects of Microgravity on the Turbidity of a Non-Newtonian Fluid Mixture of Cornstarch and Water Grade 9, W.J Keenan High School, Richland School District One Co-Principal Investigators: Cedric McQueen, Ryan Mathews, Tevin Glover Teacher Facilitator: Kirstin Bullington Proposal Summary: My group’s research question is, “How does microgravity effect the turbidity of a Non-Newtonian mixture, cornstarch and water?” Turbidity is the measure is the measure of light that can pass through a water sample. When the turbidity of a mixture is higher, the temperature is higher due to absorbed heat. Cornstarch is obtained from the endosperm of the corn kennel. In regular gravity, this non-Newtonian fluid is hard when you hit it hard or fast, but when you operate in a slow motion it acts like a liquid. When left to settle, the mixture separates somewhat due to gravity, so we were curious if microgravity would affect the initial mixing and then its settling. We plan to use a Type II FME, in which cornstarch should take up 6.9ml of the tube, and distilled water should take up 2.3ml. The interactions requested are to first unclamp the FME and shake vigorously to create the mixture. Before leaving the ISS, we request that the FME be reclamped in its original place. That way, despite agitation during re-entry and shipment, we can compare the turbidity of the two samples to determine how well the sample mixed and stayed mixed in microgravity. The same setup will be used in regular gravity for comparison to determine what effect, if any, microgravity had on the non-Newtonian fluid mixture. Turbidity will be measured through a myDaQ turbidity sensor and by spectrophotometer.

HONORABLE MENTION FINALISTS: The Effect of Microgravity Exposure on crystallized Halobacterium sp. NRC-1 Growth Grade 9, W.J. Keenan High School, Richland School District One Co-Principal Investigators: Kynda Beckett, DeShawna Black, Victoria Chandler Teacher Facilitator: Kirstin Bullington Proposal Summary: Microgravity is the condition in which people or objects appear to be weightless. The purpose of our project is to determine the effect of microgravity exposure on crystallized Halobacterium sp. NRC-1 growth on BSYC agar (when returned). The question to be addressed is “What is the effect of microgravity exposure on the growth of Halobacterium sp. NRC-1 once plated and grown on BSYC agar?” Little is known about Halobacterium, but what we do know is that they are extremophile bacteria that live in water with high salt concentrations (S. DasSarma, 2014) and are prokaryotic specimens. It makes sense to conduct this experiment due to halophiles having very little testing in space due to its response to microgravity. This bacteria requires high levels of NaCl (salt) to grow. NaCl is required because they cluster close together rather than far apart like other archaea to create sequences of 16srDNA. We hypothesize that the bacteria (halophiles) growth rates will decrease in microgravity. We already know that there are different ways to grow Halophiles. Depending on the different solutions used, the bacteria in that will determine the growth rate and effect. In our projects, the independent variable is microgravity, the dependent variable is the differences between the ground-truth FME and the space FME populations of crystallized Halobacterium sp. NRC-1, to be measured by colony count once plated upon return. How does microgravity affect the rbcL gene sequence in Rosa radrazz? Grade 9, W.J. Keenan High School, Richland School District One Principal Investigator: Nya Davenport Co-Investigators: Jada Bouknight, Christasia Scott, JaQuaris Tobias Teacher Facilitator: Kirstin Bullington Proposal Summary: This experiment is being done to determine how microgravity affects the DNA of Rosa radrazz, known as knockout roses. The knowledge that we will get from our experiment will help us understand plants and the way they work, allowing us to figure out new ways to support plant life in space, specifically chloroplast DNA. Also, according to an article by Dr. Anireddy Reddy, “Plant Growth in Microgravity”, “The mechanisms involved in gravity signal perception and transduction are intensely investigated in ground-based experiments using a variety of approaches such as clinostats, mutants, and changing the position of plants with respect to gravity.” However, not much is known about the effect of microgravity on various qualities of plant development due to the inability to create microgravity conditions on Earth for a prolonged time. Our experiment answers the question “Does microgravity exposure affect the sequence of the rbcL gene in Rosa radrazz when compared to the rbcL sequence from the same plant in Earth’s gravity?” We will be harvesting a leaf of a Rosa radrazz and preserving in 91% isopropyl alcohol to prevent its DNA from degrading from decomposition. When the FME comes back we will extract the leaf DNA, isolate and amplify the rbcL gene through PCR, and compare sequences, following the DNA barcoding procedures outlined by DNALC. The hypothesis of our experiment is that if the rbcL gene in Rosa radrazz is exposed to microgravity, then more changes in the rbcL nucleotide sequence will be detected.
15. North Charleston, South Carolina Jump to North Charleston’s Community Profile SELECTED FOR FLIGHT: How does Spaceflight Affect the Detachment of Zinc Whiskers? Grade 11, Palmetto Scholars Academy, South Carolina Public Charter School District Co-Principal Investigators: Kayla Capitan, Gabriel Voigt Teacher Facilitator: Kellye Voigt Proposal Summary: How does spaceflight affect the detachment of zinc whiskers? Metal whiskers cause large-scale damage to electronics by interfering circuits and electronic interfaces. These tiny threedimensional crystalline structures cause great damage, although most whisker-induced failures are left unreported due to lack of understanding and proper analysis methods. Although zinc was used to mitigate tin-whisker failure modes, zinc has displayed full capability of disrupting electric circuits and creating undesired connections between these circuits, resulting in shorts. The scientific community has limited knowledge and understanding of the behavior of metal whiskers, especially of detachment and of zinc whiskers, putting this experiment at the culmination of whisker behavior and whisker failure mode comprehension. HONORABLE MENTION FINALISTS: How does Microgravity Affect Kevlar Fibers Immersed in an Aqueous Solution?

Kayla Capitan and Gabriel Voigt examine a whiskered zinc-plated floor tile with a 30x camera zoom and a iPhone 6 Plus.
Proposal Summary: How does microgravity affect Kevlar fibers immersed in an aqueous solution? With increased interest in complex space missions, materials that express high-strength capabilities and high performance such as DuPont’s Kevlar XP S104 are required to provide protection. Kevlar is a material more commonly used for the production of protective vests and equipment. This experiment will immerse Kevlar fibers in an aqueous solution in order to mimic potential humid environments or condensation. If the DuPont product Kevlar XP S104 fibers proves resilient enough for spaceflight the use of these fibers should be evaluated to enhance equipment (from space suits, vehicles, spacecraft, etc.). If Kevlar is applied to 3D printing, it will strengthen and improve the materials’ abilities. Carbon 3D printers combine the rubber-like qualities of thermoplastics and the strength and durability of carbon fibers, like Kevlar. Opportunities like the use of Kevlar can lead to transforming the ISS into a functional additive manufacturing network that will advance astronauts’ abilities and safety. Since Kevlar fibers are so versatile, its potential applications are boundless. The Effect of Microgravity on the Antimicrobial Activity of methicillin against Staphylococcus epidermidis Grade 10, Palmetto Scholars Academy, South Carolina Public Charter School District Co-Principal Investigators: Aiden Durand, Griffin Eslinger Teacher Facilitator: Niquie Ragland Proposal Summary: This experiment will test how microgravity affects the antimicrobial activity of methicillin against the bacteria Staphylococcus epidermidis. During the experiment, methicillin will be introduced to a culture of S. epidermidis in both microgravity and on Earth. A type 3 FME will be used, containing methicillin, agar and water, and S. epidermidis. The bacteria culture will be activated with the agar and water, then methicillin will be introduced to kill a portion of the population. When the FME returns to the team, they will analyze the live/dead ratio of bacterial cells. The analysis will be done by staining a small sample of the bacteria, and counting how many are stained under a microscope and comparing with the number of unstained cells. A flow cytometer may also be used to determine how many cells died. The results of this experiment can be used practically to prescribe antibiotics to astronauts. Methicillin has been used to test the penicillin family of antibiotics, and S. epidermidis is a commonly used bacteria that is easy to grow, and is closely related to some commonly pathogenic bacteria such as Staphylococcus aureus. The team hopes to find a significant difference, which can be used to recommend the appropriate type or amount of antibiotic to keep for astronauts who may become sick on longer missions so that they can perform their jobs.

Knox County, Tennessee Jump to Knox County’s Community Profile SELECTED FOR FLIGHT: Testing the Effectiveness of Tobramycin and Dexamethasone Ophthalmic (Tobradex) on Staphylococcus Aureus Type of Bacterial Conjuntivitis in Microgravity Grades 7-8, Bearden Middle School, Knox County Schools Co-Principal Investigators: Moamen Emara, Alex Hoffman, Elise Kersch, Jack Lathrop, James Pierce, Mauricio Sanchez, Riley Speas, Katherine Trent, William Walker Teacher Facilitators: Kayla Canario, Virginia Brown Proposal Summary: Bacterial conjunctivitis is a common infection and can affect astronauts during space travel. As space travel progresses, bacterial conjunctivitis could become a problem. We hope to address this problem by finding out if bacterial conjunctivitis will be affected by a normal antibiotic treatment. By doing this experiment, we hope to better understand the growth and treatment of bacterial conjunctivitis. Understanding the growth and treatment will not only allow us to effectively treat future infections, but will have implications of treating other bacterial infections in space as well. HONORABLE MENTION FINALISTS: Sea Monkeys to the Rescue Grade 6, Halls Middle School, Knox County Schools Co-Principal Investigators: Reagan Frye, Summer Keck Collaborator: Rehtaeh Sutton Teacher Facilitator: Jennifer Tidwell Proposal Summary: We would like to send Brine Shrimp, most commonly known as Sea Monkeys into microgravity to understand how the lack of gravity affects the development of Sea-Monkeys. Sea-Monkeys are a group of crustaceans that undergo cryptobiosis and are sold in hatching kits as novelty aquarium pets. Sea-Monkeys should be sent into microgravity because they are extremophiles and can help us understand if life exists elsewhere in the universe. For example, the recent discovery of water, with high sodium content on our neighboring planet Mars could provide an extension to this experiment if Brine Shrimp can develop adequately in microgravity. They could be sent as an experiment to live in this or other extreme conditions to test if life could exist in other locations in our solar system.

Analyzing the Affect of Microgravity on Germination of Squash Seeds Grade 6, Halls Middle School, Knox County Schools Co-Principal Investigators: Alyssa Morgan, Riley Turpin Collaborator: Rehtaeh Sutton Teacher Facilitator: Jennifer Tidwell Proposal Summary: We want to see if the Yellow Crookneck Squash, which is a type of Curcurbita Pepo (Summer Squash) will germinate in microgravity. The reason for us wanting to conduct this experiment is to see if the seed does germinate in what is seemingly no gravity, then the astronauts stationed at the International Space Station could grow Yellow Crookneck Squashes and have another food source that is not dried and doesn’t contain chemicals. It would be an additional fresh and healthy alternative for astronauts.
17. Bullard, Texas Jump to Bullard’s Community Profile SELECTED FOR FLIGHT: Microgravity’s Effects on Solanum tuberosum Resistance to Phytophthora infestans Grade 9, Bullard High School, Bullard Independent School District Co-Principal Investigators: Emma Rhyne, Valerie Vierkant Co-Investigators: Emmalie Ellis, Raelee Walker Teacher Facilitator: Alaina Cannon Proposal Summary: Phytophthora infestans (Potato Blight) is a fungus-like protist that has caused many crop failures throughout the world, including the historical Great Potato Famine in Ireland . This protist invades the leaves and spreads to the tubers, killing the plant within days. Unless quickly disposed of, the infected plant will spread the disease throughout an entire field. Potato Blight cannot be killed, but varieties of potatoes have been discovered that are naturally resistant to the protist. The primary goal of this experiment is to determine how microgravity affects Solanum tuberosum resistance to Phytopthora infestans. Considering the potential need for future crops in space, it is important to expand our knowledge on microgravity farming. Little is known about the effect of microgravity on Solanum tuberosum,and even less is known about blight-resistant varieties. In this experiment, a sample of a blight-resistant Solanum tuberosum will be exposed to P. infestans aboard the International Space Station (ISS) and compared to our control, which will be conducted on Earth in normal gravity. Previous experiments have shown that members of the family Phytopthora demonstrate increased virulence in microgravity. The secondary goal of this experiment is to investigate how naturally blight-resistant varieties of S. tuberosum protect themselves from infection. This experiment will provide further insight to the poorly understood resistance mechanisms of certain varieties of S. tuberosum. We believe this experiment’s results will show the blight-resistant potato is more susceptible to P. infestans in microgravity as compared to normal gravity conditions.

HONORABLE MENTION FINALISTS: Effects of E. coli on Sharkskin Surface in Microgravity Grade 11, Bullard High School, Bullard Independent School District Co-Principal Investigators: Matthew Bradley, Ashley Kethan Co-Investigators: Alyssa Fowler, Elise Humphries, Trevor Johnson Teacher Facilitator: Carl Logan Proposal Summary: Our experiment is attempting to observe how bacteria spreads under the effects of microgravity, while on a surface similar to that of a shark’s skin. It is believed that by conducting this experiment, the risk of the spread of bacteria in microgravity will be reduced, where astronauts’ immune system function is substantially lowered. A common bacteria that has an easy time spreading will be used, so it was decided that a strain of Escherichia coli, or better known as E. coli bacteria, would be best. The specific strain being observed is Escherichia coli 04-3529 (Migula) Castellani and Chalmers (ATCC® BAA-2649™). There will be a dormant form of the bacteria, and it will be activated so that it has the ability to spread. The bacteria will then be returned to its dormant state so its growth, before returned to Earth, is stopped. Upon return, the bacteria will be studied under a microscope to determine how the bacteria spread in microgravity. The surface used will be acquired from Sharklet Technologies. This surface is modeled to replicate a shark’s skin. Shark skin is known for prohibiting the growth of bacteria, so it will be ideal to use in our experiment. A ground experiment will also be conducted here on earth. The results from both of the experiments (the one on ISS and the one on earth) will help to determine whether or not shark skin surfaces are as effective in microgravity as they are here on the earth. The Dissolving of Kidney Stones in Microgravity Grade 11, Bullard High School, Bullard Independent School District Principal Investigator: Jake Timme Co-Investigators: Wes Carter, Hunter Granske, Tucker Pine Teacher Facilitator: Carl Logan Proposal Summary: Many health issues can arise when one is in space for an extended period of time. Our bodies are not made to live in a microgravity environment. Kidney stones are one of the many effects space has on the body. Kidney stones are hard crystals that develop in the kidneys, and they can cause tremendous amounts of pain and discomfort to the people that are in space the same way they affect people here on Earth. Being able to dissolve the stones while in the extremes of microgravity is an important aspect in long term space stay. We plan to make synthetic kidney stones on earth, then send them into microgravity to test how they dissolve, while conducting the same experiment simultaneously here on Earth. The results of this experiment will give us a better idea on how to treat this health issue in microgravity.
18. Burleson, Texas Jump to Burleson’s Community Profile SELECTED FOR FLIGHT: Kidney Stone Conundrum Grade 5, The Academy at Nola Dunn, Burleson Independent School District Co-Principal Investigators: Hannah Greenhill, Caleb Quisenberry, Cooper Williams Teacher Facilitator: Riki Bunch-Pettigrew Proposal Summary: We propose to answer the question: Does microgravity have an effect on the disintegration of kidney stones (nephrolithiasis) in chanca piedra (phyllanthus niruri)? This information will let us know if chanca piedra will help astronauts with their frequent kidney stone issue. If they do not dissolve in microgravity, we will have to find an alternative solution. On Earth kidney stones are painful and stress causing, but with the frequent number in space they waste important time they could be using to do their jobs. They spend nine hours of their day researching and working on their projects, eight hours sleeping, and about an hour to have a meal because they have to heat the food, catch it, then eat it. Also, exercising two hours a day helps astronauts prevent bone and muscle loss. In our test we will simulate chanca piedra dissolving kidney stones in the human body. We want to prevent kidney stones for astronauts. We will put two kidney stones in volume one, volume two will have chanca piedra, and volume three will be filled with formalin. We will test this on Earth and in space then compare how much they dissolved. The result of this experiment might reduce the amount of time the astronauts deal with kidney stones. It will let us know if the astronauts will still have to go through all the pain as well. If they did not pass kidney stones so often they could be solving problems to help them live in space. HONORABLE MENTION FINALISTS: What are the Effects of Amoxicillin Fighting Against E. Coli in a Microgravity Environment? Grade 6, Kerr Middle School, Burleson Independent School District Principal Investigator: Delaney Storey Co-Investigators: Trinity Conard, Karis Knifley, Bailey Lasater Teacher Facilitator: Lana Sather
Academy at Nola Dunn students prepare to “grow” kidney stones in order to fine tune their experiment for flight.
Proposal Summary: We propose to answer the question of what Escherichia Coli will do when exposed to amoxicillin. Our team is looking forward to finding out if amoxicillin will successfully fight E. Coli. We believe that the amoxicillin will fight Escherichia Coli better due to less gravity. Amoxicillin is an important material as it is used to fight multiple bacterium such as salmonella, ear infections, E. Coli, and some strains of strep throat. It is important to study what amoxicillin will do to Escherichia Coli in space because if one astronaut gets bacterium in their system we will know to use amoxicillin. We are dreaming big and hopefully one day there will be space colonies with hospitals and varieties of different medication including amoxicillin. Our research has shown that E. Coli is effectively treated with amoxicillin in regular Earth gravity. We plan to use a Type 2 FME with one clamp containing live E. Coli on one side and on the other amoxicillin. Once it reaches the ISS the amoxicillin will be introduced to the live E. Coli. The Effect of Radiation on DNA in Microgravity Grade 6, Hughes Middle School, Burleson Independent School District Co-Principal Investigators: Belle Ann Davis-Hernandez, Emma Dustin, Emma Fritz, Presley Galland Teacher Facilitator: Doug Cline Proposal Summary: We, as a group, want to see the effects of radiation on fixed pig blood cells. From what we have learned, we think that when an astronaut is up in space for a long time with high radiation levels that their DNA methylation process is altered so when an astronaut comes back down to earth they are more likely to get different types of cancer. Also, to get certain genes turned on and off means your expressed DNA will be changed. The astronauts offspring could possibly have the same genetic changes as the astronauts have, they most likely will have a higher risk of getting cancer just like their parent because the DNA will have the possibility of being passed on. This type of epigentics is what our group is interested in doing. For this experiment we will be using an FME type 1 tube that uses no clamps.Volume 1 includes blood cells that are fixed in formalin. We are using the whole 9.4 ml of space in the tube for volume one. Our hypothesis is if the pigs blood is exposed to high radiation levels then the epigenetics will be altered through the DNA methylation process. Dr.Bobby LaRue will be testing the pig blood cells after the cells are returned from ISS they will be the at the University of North Texas.
19. Houston, Texas Jump to Houston’s Community Profile SELECTED FOR FLIGHT: pGLO Plasmid Transfer in Escherichia coli as a Means to Track Antibiotic Resistance in Microgravity Grade 11, Cesar E. Chavez High School, Houston Independent School District Co-Principal Investigators: Esmeralda Cervantes, Ashley Olvera Co-Investigators: Omar Compos, Esmeralda Pantoja Teacher Facilitator: Dr. Jason Busby Proposal Summary: It has been proven that bacteria grow and interact much differently in space. In the past, NASA sent disease causing bacteria into space to observe its growth. However, studies are very limited in the area of bacteria transferring genes or plasmids for antibiotic resistance in a microgravity environment. The purpose of this study is to explore this area via the transfer of the pGLO plasmid carrying a gene for ampicillin resistance among colonies of Escherichia coli. Bacterial growth and antibiotic resistance transfer will be measured in an FME Type 1 modified into a common bacterial slant. Growth will be observed and measured on a periodic basis while the sample remains in orbit. The pGLO plasmid is being used due to its nature of glowing under a UV light source making observation of transfer easily observable with a small handheld UV light and the human eye. Possible implications for this experiment could lead to modification of treatment for astronauts on missions; and possibly before missions to condition the immune system, based on how the bacteria interact in a microgravity environment. HONORABLE MENTION FINALISTS: Regeneration of a Sea Cucumber Grade 11, Cesar E. Chavez High School, Houston Independent School District Co-Principal Investigators: Juan Calderon, Brandon Chacon, Jonathan Gutierrez, Luis Jasso, Moises Trevino Teacher Facilitator: Anastasia Martynenko
Chavez High School SSEP Flight Team preparing pGlo Plasmid.
Proposal Summary: Our project involves studying the process of regeneration. To do so we will be sending a Sea Cucumbers called Euapta lappa up into ISS. A sea cucumber is an animal similar to a slug that when wounded or cut can regenerate its body parts. It is this specific process in which the sea cucumber is regenerating its body parts that we wish to analyze in order to understand more of what aids the process, if there are any defects, and how the skin and body parts are reconstructed. In order to get the sea cucumber into space, we will be sending the Sea Cucumber using the Type 3 mini lab with one clamp blocking the fixative and the other so that the sea cucumber and its water with algae be on one side. The Effects of Microgravity on the Preservation Ability of Sodium Silicate Grades 11-12, Cesar E. Chavez High School, Houston Independent School District Co-Principal Investigators: Daniel Banda, Cesar Cruz, Yasmine Vasquez Teacher Facilitator: Anastasia Martynenko Proposal Summary: Sodium Silicate was first observed by Jean Baptist van Helmont, circa 1640 and from its conception it had a lot of uses. Liquid Sodium Silicate, (aka water glass) has been used to preserve organic food such as eggs here on Earth similarly to vinegar with pickles; and Solid Sodium Silicate can also be mixed with water in order to create a gel-like substance that can create a seal for broken car parts related to the engine or the substance can be placed over a broken pipe in order to stop a liquid from leaking which makes it a good and quick repair material to extend the life of pieces. So you can say that Sodium Silicate has many uses for us here on Earth, therefor Sodium Silicate is an important human made substance as a quick fix or as a preservative. We wanted to be test Sodium Silicate’s ability to preserve eggs but due to the limitation of the FEM tube width we are going to compromise and use a semi-permeable substitute: a blueberry. Therefore our question is: “What affects does microgravity have on Sodium Silicate’s ability to preserve food stuff like blueberry?” If our hypothesis is correct, the Sodium silicate should keep out the moisture and decrease the rate of decay and extend the berries lifespan. In translation, the results should be similar if we used an egg.
20. McAllen, Texas Jump to McAllen’s Community Profile SELECTED FOR FLIGHT: The Effects of the Perchlorate Ion in Simulated Martian Soil on Solanum lycopersicum Seed Germination in Microgravity Grade 11, IB at Lamar Academy, McAllen Independent School District Co-Principal Investigators: Sabrina Benitez, Sofia Escobar, Juan Pablo Flanagan Advisors: Marc Braden, Dr. Anxiu Kuang, Dr. Michael Wayne Persans Teacher Facilitator: Laura Nikstad Proposal Summary: One of NASA’s many current projects, and one the general public has been waiting for ever since we set foot on the Moon, is the human mission to Mars. The recent discovery of liquid water on Mars has increased our anticipation of this dream; however, along with water, it has been found that Martian soil contains high levels of magnesium perchlorate—a contaminant toxic to humans. Analyzing the results of the experiment will provide insight into the effects of perchlorate, combined with microgravity, and how these unfamiliar conditions will affect the possibilities of ever establishing a sustainable colony on Mars. Future manned missions to Mars are in the works and questions about nutrition and sustainability must be answered. This experiment will give us a greater understanding of food growth on Mars, a planet with a significantly smaller amount of gravity than Earth. On the ISS, our Type 3 FME mini-lab will contain Martian simulated soil with tomato seeds and distilled water to catalyze the germination. After twelve days, a solution of 10% Neutral Buffered Formalin will be added to the soil in order to halt the growth and “freeze” any viable data so that we may be able to observe the tomato sprout on Earth and compare the results to the control groups in order to find how plants that have evolved to fit Earth’s conditions will grow and survive in conditions very different from our own.
Juan Pablo, Sofia and Sabrina are conducting experiments to determine germination failure rates in tomato seeds to inform how they will pack their FME.
HONORABLE MENTION FINALISTS: Effects of Microgravity on Algae Growth Grade 11, IB at Lamar Academy, McAllen Independent School District Co-Principal Investigators: Roberto Iglesias, Nicolas Restrepo, Carlos Sanchez Advisor: Dr. Hudson DeYoe Teacher Facilitator: Laura Nikstad Proposal Summary: Algae are unique plants that are greatly used for research due to their variety of sizes and types as well as their simplicity. The size of algae ranges from the microscopic level to large seaweeds and can be grown using water that does not need to be perfectly clean. For our experiment, we dealt with the green algae known as Scenedesmus in order to determine if the growth of algae differs in microgravity compared to on Earth. We chose this algae due to the fact that it can grow in the absence of light, surviving on glucose and water (Scenedesmus). A main reason for why algae is so special is it has a large variety of uses that can benefit in space travel. One major use for algae is as a fuel source; algae can be grown to produce biodiesel, bioethanol, biobutanol, hydrogen, and biomass. These fuel sources may be used in the engine and may also be used for electricity. Another purpose is as a food supplement since algae contains protein, carbohydrates, and fatty acids useful for energy (Uses of Algae). Our procedure to observe the change in the growth of Scenedesmus (if any) was to have the Scenedesmus be mixed with nutrient filled water and stop its growth using Formalin (2 days). This allowed us to have a set amount of time that the Scenedesmus would be growing for both in microgravity and on Earth. The growth of the Scenedesmus would then be observed using a microscope. The Effects of Microgravity on Gastric Acid Digestion of Proteins Grade 11, IB at Lamar Academy, McAllen Independent School District Co-Principal Investigators: Calvin N. Beck, Gabriela S. Pena, Alejandro M. Vail Teacher Facilitator: Marc Braden Proposal Summary: In future human space travel, humans will have to live and adapt to microgravity, and thus perform all of their vital functions, such as respiration and digestion, without the help of gravity. On Earth, gravity does not only affect the human skeletal and muscular systems, but affects all of the bodily functions, including the digestive system (The Body in Space). The digestive system, primarily responsible for the transformation of food into energy, requires the solid energy sources entered into the mouth to be broken down before translating them into energy forms such as glucose, which cells use for respiration (Human Body Digestive System) . Gastric acid — a strong, hydrochloric acid-based substance that includes the enzyme pepsin — plays a significant role in digestion in humans, as the main solvent of proteins in the body (Human Body Digestive System, My Favorite Protein: Pepsin). As humans embark on longer and longer missions, even the small effects on the astronauts will become more apparent, as they are forced to live in those unnatural conditions for even longer amounts of time. This brings up the question: “What are the effects of microgravity on gastric acid digestion of proteins in the human stomach?” The experiment will compare the length of proteins after a specified period of time in the experiment conducted on earth and in the International Space Station’s microgravity environment. Researchers can use the conclusions drawn from this experiment to help plan future missions to space and minimize the effects of microgravity on future astronauts.
21. Bellevue, Washington Jump to Bellevue’s Community Profile SELECTED FOR FLIGHT: Arabidopsis thaliana Germination in Martian Soil Simulant Grade 7, Open Window School, Northwest Association of Independent Schools Co-Principal Investigators: Subi Lumala, Vivienne Rutherford, Catherine Whitmer Teacher Facilitator: Brian Preston Proposal Summary: Arabidopsis thaliana are plants that are highly experimented on. Our experiment is an investigation to see how they will grow in microgravity, and in a soil similar to that of the surface of Mars. Arabidopsis thaliana would be useful to have on Mars because of its experimental potential. It is not possible on Earth to simulate the lower gravity of Mars, so microgravity provides a test of lower-than-Earth gravity. The gravity on the ISS is almost 0 m/s2, the gravity on Mars is 3.8 m/s2 (Universe Today), and the gravity on Earth is 9.8 m/s2 (Universe Today). Gravity on the ISS allows us to test plant growth in an environment closer to the gravity on Mars. HONORABLE MENTION FINALISTS: Pectobacterium Hydrolyzation of Polysaccharides in Microgravity Grade 4, Open Window School, Northwest Association of Independent Schools Co-Principal Investigators: Nolan Daniels, Bess Hurlock, Sonja Larson, Nathan Wen Teacher Facilitators: Erica Mahoney, Randy Hollinger Proposal Summary: Will plant tissue from Solanum tuberosum (potato) be more resistant to the plant pathogen bacteria Pectobacterium carotovorum in microgravity? Pectobacterium carotovorum makes plant cells lose their “grip” with each other by destroying the polysaccharides between the cell walls. We chose Pectobacterium carotovorum (formerly Erwinia carotovora) because it is easy to keep for long periods of time and is important in learning about keeping plants healthy. We saw in other research that NASA is interested in how plants grow in space, so we thought it would be interesting to see how they fight disease. The particular strain of bacteria that we propose to use has a plasma DNA GFP gene (green fluorescent protein) that allows us to study the plant with an ultraviolet light when it returns to us to see where the bacteria decided to grow. After contacting an expert (Dr. Amy Charkowski – University of Wisconsin Plant Pathology), we decided not to use a carrot as we wanted to at first and instead to use a Solanum tuberosum as our test subject because it will last long enough for the microgravity experiment. We are also going to use highly sterile water to keep the Solanum tuberosum in good condition for our experiment. We will use an FME 2 with one clamp so we can have the astronauts release the Pectobacterium carotovorum into the Solanum tuberosum to see the effect. We believe that without gravity, the Solanum tuberosum will be more resistant than our experiment on Earth.
Open Window School seventh graders Vivienne Rutherford, Catherine Whitmer, and Subi Lumala conduct experimental trials with various numbers of Arabidopsis seeds in simulated Martian soil in order to optimize their FME flight configuration.
Hydroponics Germination in Microgravity Grade 5, Open Window School, Northwest Association of Independent Schools Co-Principal Investigators: Ava Arabshahi, Claire O’Connor, Anika Thomas Teacher Facilitator: Danalynn Coulon Proposal Summary: Our team aims to study whether hydroponic plant germination would work in microgravity because of the differences in pressure and gravity levels compared to earth. Hydroponics is growing plants without dirt, just with water and fertilizer. Plants growing on earth rely on a small amount of gravity to spread roots. We want to investigate if hydroponics will be able to germinate in microgravity and low-pressure conditions in space. In the proposed experiment, we plan to use alfalfa and medallion seeds, Rockwool cubes as the growing environment, and FloraGro as fertilizer. We have conducted two trials on earth, using basil and ryegrass seeds, cotton balls for the growing environment, and banana peels as a natural fertilizer (alfalfa seeds, medallion seeds, and Rockwool cubes were not available to us at the time of our trials). Our trial experiments demonstrated that both our basil and ryegrass seeds germinated successfully in about seven days. According to our research, alfalfa and medallion seeds also germinate in about six to seven days. This proposed experiment is important because its results can help astronauts harvest fresh food while in space. Both of these plants are edible and high in nutrients. Currently, astronauts have to eat dried foods, which, after a while, get boring. Also growing with dirt may be difficult because dirt weighs more than water. Water already exists on the ISS. The hydroponics technique may be applied to any type of seed, which can be very useful.
