Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

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 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.

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

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

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

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

Learners develop an understanding of air pressure in two different activities.

Learners build devices from rubber bands to test for invisible air pollutants.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.
