In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

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.

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

In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.

In this activity, learners build small animated toys that move.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

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

In this activity, learners explore the history, design and motion of spinning tops. Learners work in teams of "engineers" to design and build their own tops out of everyday items.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

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 activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

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

Learners construct a rocket from a balloon propelled along a guide string.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.
