In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.
