In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.
