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.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners explore mammal locomotion by constructing flipbooks.

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.
