Support your students’ learning with our handbooks: they’re full of interaction hints, discussion questions and insider intelligence.
Discover how simple machines work. Use a lever, screws, wheels and axles, inclined planes, wedges, and pulleys to send satellites into orbit, split an iceberg, make music, and more!
Conduct your own experiments. Change each machine and see what happens: can a scooter travel as fast and far as a bike? How many pulleys do you need to lift a spaceship?
