How did the ancient Egyptians build the pyramids? How do we build giant skyscrapers today? To understand these marvels, you need to understand simple machines such as levers and inclined planes. Machines& Motion contains 35 lessons that will teach your child about simple machines and the laws of motion, which are the basic principles governing the physical world around us. But this study is anything but dull. Your child will enjoy experimenting with friction, racing roller skate cars, and making pendulums in this hands-on curriculum about how things move.
