Read all about weight, mass, work and power. Then do the test!

Watch the animation on energy, work, kinetic and potential energy.

Read all about work, kinetic energyand potiential energy and how it applies to theme park rides. Then do the test!

Run the simulation. Learn about conservation of energy with a skater dude! Explore different tracks and view the kinetic energy, potential energy and friction as he moves. Build your own tracks, ramps and jumps for the skater.

Find out about the science behind electricity generation and some of the issues facing us in the future. Then have a go at the games and quizzes.

How to do an experiment to show what happens when you try to stretch sweets.

A game for you to make! A large marble is rolled along a track made from a commonly available and inexpensive metal shelf bracket. The track is gently bent so that there is a flat portion, then a small hill, and finally a steep uphill portion. The objective is to roll the ball so that it goes over the first hill, but does not come back over the hill -- the ball should remain in the dip between the two hills.

Pull different objects up the ramp and look at the graphs of power, work and energy.
