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.

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 explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

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

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

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

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

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.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

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.

Get all wrapped up in a lesson about skin!

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

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).
