In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

Learners build a wind turbine and test it to see how much energy is created.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this earth science activity (page 14 of the PDF), learners use layers of closed-cell foam to create their own model of the mid-ocean ridge in order to simulate seafloor spreading.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this outdoor activity, learners design devices that will catch prey or gather plants.

In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.
