In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this activity, learners construct cars that are powered by hand-made, electric propellers.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this activity, learners build styrofoam boats powered by twisted rubber bands.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.
