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.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

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

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

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 demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

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

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

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 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 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 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

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