New words are set in bold and appear with short explanations in a comprehensive glossary. Each book contains a how-to-make activity page, a list of books for further reading and an index. WHEELS AND AXLES explains the principles of rolling and the uses of different types of wheel. Familiar objects are depicted in photographs to aid understanding.
