In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

"Molecules in Motion" explores how materials behave and change in a vacuum.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
