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

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

In this activity, learners explore physics by building a catapult that launches marshmallows with household objects.

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

When baseball was in its infancy, the ball had plenty of bounce. Today's baseball may not seem to have bounce to it at all; if you drop a ball on the field it won't bounce back.

Learners attach an egg to a rubber-band bungee cord and drop the egg.

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

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

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

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

Build your own version of the classic physics toy using simple materials.
