To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

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 try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this activity, learners discover a trick to release the air out of a balloon without popping it.
