In this engineering activity, learners explore simple machines and then build cardboard automata using cams.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this three-part math activity, learners explore shapes. In part one, learners identify, describe, and classify two-dimensional shapes.

In this activity, learners explore the engineering and principles behind working elevators.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.
