In this activity, learners investigate the properties of different types of balls.

In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

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

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

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