In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

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 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.

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 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 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.

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

Use a homemade potato launcher to explore air pressure. This activity includes simple instructions on how to build a homemade propulsion pipe using pipe, a wooden dowel and duct tape.

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

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

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.
