1) The document outlines activities done by students exploring polymers, including changing polymer pellets, identifying polymers in products, and experiments on viscosity and strength of polymer films. 2) The students designed a humidity sensor using a polymer film that changes color with humidity. 3) They proposed developing an anti-microbial medical gown by adding an anti-microbial polymer to areas with most patient contact, to reduce microbial transmission and contamination. They hypothesized this polymer would improve gown properties and resistance to infection.
