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.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

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.

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

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

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

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 weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

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

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

In this activity, learners will determine if the frequency and intensity of hurricanes are changing using real data from the National Hurricane Center.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this online Flash game, learners will captain a sailing challenge, adjusting boat direction and sails, seeking the way to take greatest advantage of varying wind speeds and directions to catch the

In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.
