Amazing Inventions that Made Life Easier.
This book strips the technicalities of machines - from a pair of pliers to cranes, wind turbines, power drills - right down to the basics. It shows how the simplest of devices and scientific principles form the basis of the most complex machines. Readers will be able to look at the working world around them with fresh understanding.
Colour artworks show inside views and help explain the principles of wheels, pulleys, gears and levers, and practical experiments to do at home increase understanding, and reinforce the learning experience.
This is a book to immediately capture the interest of independent young readers, and for families and school groups to explore together.
