That's the Way the Ball Bounces: Level 1
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

That's the Way the Ball Bounces: Level 2
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

Plastics the Second Time Around
Source Institutions
In this activity, learners test and compare the physical properties of thermoplastic polymers. Learners compare different plastics based on their color, degree of transparency, texture, and density.

What's the Matter
Source Institutions
In this activity, learners identify different classes of matter based on physical properties.

As Light as Air
Source Institutions
Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.
