In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

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

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

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

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

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

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

In this activity, learners make their own "tornado" using two soda bottles and water.

In this activity, learners will engineer three different parachutes to test how well each one works.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.
