This title comes with 20 easy-to-do experiments and 300 exciting
pictures. It tells the story of technology, from simple gears and
levers to high-tech gadgets and gizmos. It covers all the basics of
how things work - with fascinating photographs of machines in
action, plus accessible inside-view diagrams. Practical projects
help you to make your own minimachines, including a windmill and a
vacuum cleaner! It is ideal for 8- to 12-year-olds, for home and
school use. The screw, the wedge, the lever and the sloping ramp
are the foundations of much more complicated machines. This book
explains how they work, and how they have contributed to
technological progress over thousands of years. It investigates all
kinds of devices - from a pair of pliers, to cranes, wind turbines
and power drills - right down to the basics of how they operate.
And by making their own levers, pulleys, belt drives, wheels and
more, young readers will be able to look at the working world
around them with a fresh awareness.
