In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

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

In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.

In this activity, learners will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

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.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

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 build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

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

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners build their own rockets from paper, coffee stirrers, and tape. Learners discover that when anything flies, air pressure is always involved.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Conduct a simple experiment to explore how temperature changes can make things expand or contract.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.
