This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

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.

In this physics activity, learners will explore buoyancy.

In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.

In this activity, learners explore Charles' Law in a syringe.

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.
