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.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

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

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.
