Explore Simple Machines! With 25 Great Projects
by Anita Yasuda

This book is a good introduction to the concept of mechanical advantage, which explains how simple machines make work easier. Each chapter is dedicated to each of the six simple machines: levers, inclined planes, wheels and axles, screws, wedges, pulleys. A brief history of the machine and how it works is followed by three or four activities that demonstrate the machine's usefulness. A final chapter offers tips on how to be an inventor.

Well-organized and clearly written, the book is ideal for connecting knowledge to the real world and sparking creativity.

Perfect for ages 6-9.
