In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

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

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
