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.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

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

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

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

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

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

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

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

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

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

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.

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

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