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

In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

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

In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

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.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

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 observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.
