In this simple demonstration, learners investigate the properties of air pressure. Learners place an index card on top of a glass full of water, then invert the glass.

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 activity, learners use simple items to construct a device for indicating air pressure changes.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this activity, learners explore how pneumatics and hydraulics could be used to produce movement in a robotic arm.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

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.

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

The demonstration/experiment provides quick proof that air has mass.

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

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this activity, learners construct paper airplanes that twist and turn.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

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.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

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.
