IS2505 Properties of Polymers
Polymers affect every aspect of our daily lives. From the plastics we use to the clothes we wear; polymer chemistry is everywhere. In this kit, students will perform three fun and fascinating activities involving polymers. In the first two activities, students will perform a cross-linking procedure on polymers to create polymer “worms” and the classic “slime.” In the third activity, students will investigate the properties of a super-absorbent polymer, capable of absorbing hundreds of times its own weight in water, to create instant “polymer snow.” The kit contains enough materials for 15 groups. Teacher’s Manual and Student Study Guide copymasters are included.
