In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

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

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.
