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 weather activity, learners build their own wind detector and test for the presence of convection currents in their indoor location.

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

In this activity, learners make a barometer, an instrument to measure change in air pressure.

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 weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

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 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

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

In this activity, learners explore clouds and how they form.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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

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

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
