See all formats and editions

This series offers a brief and clear introduction to simple machines: what they are, their parts and what they can be made of, how the work and how we use them to apply the forces to pushes and pulls to move, lift, make or break things.

The books contain examples of applications in the world around us and draw on examples familiar to young readers in their everyday world as well as those "hidden" in everyday objects.
