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 and 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. Elementary and middle schoolers will love the exciting, easy-to-understand, and easily taught lessons in the God s Design textbooks by Debbie and Richard Lawrence. All eleven books in the God s Design series are very comprehensive, richly illustrated, and cover material that is often left out of other curricula. You ll love the flexibility of this popular series, which is designed to be used with students ranging from first through eighth grade all at the same time. Each lesson begins with a read-aloud section that covers the basic material and is followed by a fun hands-on activity that involves your child and reinforces what you just read. Each lesson ends with review and application questions. In addition to the lessons (34 35 per text), God s Design books contain special feature articles that examine the lives of scientists throughout history who have contributed to the subject. Other articles contain fun facts. Finally, each book has a unit project that ties all of the lessons together and reinforces what the student has learned.
