The time has finally come! Our Citizen Scientists completed their experiments and sent us back the data. In total we had 91 students complete the project which gives us enough data points to answer the question we posed to them.
The results point to the petri dishes containing [2-(aryloyloxy)ethyl] trimethylammonium chloride and 2-carboxyethyl acrylate (TMA/CAA) polymer performed the best with [2-(aryloyloxy)ethyl] trimethylammonium chloride and 3-sulfopropyl methacrylate (TMA/SA) coming in second. The zwitterionic sulfobetaine methacrylate (SBMA) came in last place for the polymers, and as expected the agar growth medium used for our control showed the most bacteria of all the petri dishes.
This means that moving forward with our project, we will focus on the TMA/CAA and TMA/SA polymers. The next major step with these polymers will be to attach them to aluminum coupons which has been led by Roslyn McCormack. This link will take you to the data we received from the Citizen Scientists.
I want to thank all the students who participated in this experiment. You have performed a vital experiment, and your work will help us get our, and now all of yours, project to space. I also want to send a special thank you to Dr. Luella Stelck, who put in extra work to help us finish this project. We plan on returning to the classroom soon to present the findings and a general project update to the students. We also will be giving out swag-bags to all the students who completed the project.
