A young girl explains how simple machines, such as pulleys, wedges, and screws, work as she repairs her friend's skateboard, the mayor's flag pole, and her neighbor's scissor.

Building a fort in the backyard, a grandfather and granddaughter get help from six simple machines: lever, pulley, inclined plane, wheel and axle, screw, and wedge.

Kids use simple machines every day without realizing it. Teeth are wedges and so are knives, forks, and thumbtacks. Many toys such as slides, which are inclined planes, and seesaws, which are levers, are also simple machines. Two appealing kids and their comical cat introduce levers, wheels, pulleys, inclined planes, and more, and explain how they work. This lively introduction to physics will get kids excited about how simple machines simplify our...

"Machines help make work easier, like when you need to lift something heavy or reach way up high. There are six simple machines: the lever, the wheel and axle, the pulley, the ramp, the wedge, and the screw. Can you adjust a seesaw to lift an elephant? What happens when you combine two or more simple machines? Read and find out!"Amazon website.
