Learners follow the template to build and fly a paper helicopter.

Learners act as engineers and design mini submarines that move in the water like real submarines.

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

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.
