In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

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

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

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.

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

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

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

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.

Use this hands-on activity to demonstrate infrared and thermal radiation.

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