  1. Charlotte Goes to Space • Stephany Juarez,Aileen Lopez, Gisela Munoz, Daniela Ortega Unity Jr High School, Cicero Il

  2. Essential Questions • Can a spider egg survive in microgravity ? • Will a spider’s egg hatch in a microgravity setting ? • Will a spider’s behavior and physical characteristics change ? Our Initial Design

  3. Dead leaves start to decompose Leaf litter Isopods help break the leaf litter Terrariums Setup Collembola grace on fungus Spiders produce egg sacs fungus on its surface

  4. Leaf-litter Plastic No substrate

  5. Results • Study if spider egg sacs survive launch? • Yes • Do the spiders develop and hatch in microgravity? • Yes, 2 of the 6 egg sacs had evidence of hatching. • Do the spiders exhibit cannibalism as a food strategy? • Very Likely, 1 very large spider was found. • Do the spiders survive re-entry to earth? • No

  6. Results We sent 6 Diplostylaconcolor egg sacs. To our surprise what returned was Diplostylaconcolor Egg sac Collembola: Lepidocyrtus Fungus Spider in earth bond control test tube Mite : Schweibae Nematodes

  7. In Conclusion • We believe our spiders did not survive re-entry into Earth because : • Moisture • Too much microbial growth • Oxygen levels • Test tube time • What we would change next time : • Predetermine the amount of moisture ? • Different species ? • More replicates ?

  8. Questions

  9. We would want to thank Cicero School District 99, Unity Junior High School, Exxon Mobil, and the Wise Lab at University of Illinois at Chicago (UIC). Their support made it possible for us to participate in the Student Spaceflight Experiment Program (SSEP). Thanks to the National Center for Earth and Space Science Education (NCESSE) for guiding us throughout the project. Partner institutions
