In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

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.

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

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.
