In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

What keeps bubbles and other things, like airplanes, floating or flying in the air?

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.
