In this activity, learners build a carousel toy that spins when pushed down.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

Learners construct and launch paper helicopters.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

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

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

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