Learners test two jars containing soil, 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.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

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

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

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

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

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

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.

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

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

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

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

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

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