In this engineering activity, young learners investigate multi-level buildings.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

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

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

Learners conduct four simple experiments to demonstrate the effects of air pressure.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.
