In this activity, learners build their own construction cranes using tongue depressors and pushpins.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

This is an online Flash game where learners can experiment with ballistics and how to compensate for the varying levels of gravity found on the planets of our Solar System.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.

In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.
