Read and find out about six simple machines—the lever, the wheel and axle, the pulley, the ramp, the wedge, and the screw—in this colorfully illustrated nonfiction picture book. Machines help make work easier, like when you need to lift something heavy or reach way up high. Can you adjust a seesaw to lift an elephant? What happens when you combine two or more simple machines? Read and find out out in the proven winner Simple Machines! This clear and appealing science book for early elementary age kids, both at home and in the classroom, uses clear explanations and simple, fun diagrams to explain how machines work. This book also includes a glossary and a find out more section with a lever experiment.
