Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this physics activity, learners will explore buoyancy.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

Learners develop an understanding of air pressure in two different activities.

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.
