In this activity, learners explore clouds and how they form.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

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

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

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity, learners simulate the behavior of the atmosphere.

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
