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

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 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.
