Inclined Planes and Wedges

Focusing on simple machines and how they help us do work in our daily lives, this fun and informative series introduces young readers to several basic concepts of physics - such as work, force, gravity and fiction. In this volume, easy-to-do experiments, colourful photos, clear text and fun activities show kids how inclined planes and wedges are used, and how they make work easier. Also includes a list of websites, a further reading list, a glossary, an index and full-colour photos on every page! Ages 7-9.
