In this activity, learners build a carousel toy that spins when pushed down.

Build your own version of the classic physics toy using simple materials.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

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

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

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.
