Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

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.

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

"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.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

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

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi
