In this physics activity (page 5 of the PDF), learners will witness the effects of free fall by observing falling water, and will gain a better understanding of the concept of weightlessness.

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

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

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

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

This is an online game about stopping distance. Learners choose one of three vehicles and one of three speeds.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
