In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height. This activity is a fun way for learners to become more familiar with polymers and their uses. Safety note: The "Teacher Notes for Level 2" link contains a number of safety guidelines that should be read before doing this activity.
