Digital Footprint Assignment
The experiment is basically just testing whether or not silly putty can be made in microgravity, and if so they are testing to see how different the traits are of the silly putty that was made in microgravity vs. the one made on earth.Who: The 8th graders from Lincoln Middle School, the middle school science teachers.Collaborators: Francis Abastillas, Dean Chien, Matilda Loughmiller, Alex Soohoo, Roman Valentine and Jane Cho Watts. Principal Investigator: Cindy Yen. From where: Lincoln Middle School, Santa Monica, California. What: The experiment is trying to figure out, what’s the effect of microgravity on the formation of silly putty and how do the characteristics differ from the silly putty made on earth. Why: They did this experiment of making silly putty in microgravity to help the world learn more about non-Newtonian fluid.When: It was either June 7 2012 or between May 22-24 2012. The materials that the team used was sodium berate solution which is borax mixed with top water and Elmer’s glue. They used type 2 FME with glue in the main FME volume and sodium berate solution in the long ampoule. After it was mixed around, it became homemade silly putty. When the FME got back to earth, they will test the differences and of the silly putty made in microgravity and the silly putty made on earth. The traits that they were testing for is molecula structure, viscosity, color, hesiveness, dissolvabilisity in alcohol, bounce height, and flammability. They predict that the silly putty will be made in the ISS although the viscosity and bounce height will be different .the team hopes the silly putty in microgravity will be useful in the knowledge of non-Newtonian fluid. The difference between a control group and an experimental group is, one group is exposed to the conditions of the experiment and the other’s not.You change a variable in the experimental group to see if the outcome is dependent on in. With the control group, you don’t change anything to compare it to the results of the experiment group. Experimental Group: Where the experimental procedure is performed. This group is exposed to the independent variable being tested and the changes are observed and recorded. Control Group: This is where the independent variable being tested cannot influence the results. This isolates the independent variable’s effects on the experiment and can help rule out alternate explanations of the experimental results. I think this team may have won because they were organized, they worked as a real team ad they’ve got determination to do this project. They did a lot of researches too so that was really helpful.
