Or you could draw a box underneath it and watch it bounce on it. You could change the material of the block, or change the gravity. You can even hang the ball from a string or a spring and graph the effect. Environments or models where you can change velocity, gravity and so-on. Examples include the battery, the electric motor, and the photocopier.
Pupils can browse pages and gain explanations of scientific principles.
Terms such as electrons are described and a few working models - such as the mixing of coloured light are particularly useful, as well as being humorous. An inventors book shows who invented what and a history section shows the inventions on a time line. Tutorial style look at forces with sections on motion, stability, pressure and more. Of particular interest is the laboratory section where a few useful experiments can be performed. The experiments involve friction, gravity, stopping distances and Newton's second law.
