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.

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

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

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

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

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

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 activity, learners build a hovercraft using a paper plate, cup, and simple motor.

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

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.

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

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

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

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

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

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