In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.

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 create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi
