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.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

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

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

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 conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

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).

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 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 simulate the behavior of the atmosphere.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
