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

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 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.

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.

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.

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

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 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.
