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 (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

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.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

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

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

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

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

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

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

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.
