Each book introduces a particular principle and then explores how it is used in different and increasingly complex gadgets and machines.

Artwork and photographs help to explain the workings of machines.

New activity spread allows children to investigate the principles for themselves.

Fresh new design and eye-catching fact boxes motivate young readers.
