What do bones do for you? What would happen if you didn’t have any bones?  Could you run and jump? Second grade readers will find out in this fun and fascinating look at the world of bones. This is a wonderful addition to the “Searchlight” books series. After an introduction, the author launches right into the substances that make up bones. For children, marrow and hard bone are surrounded by cartilage and the periosteum. What are the ways bones help you function? From protection to hearing to keeping you upright, there are many groups. The rib cage protects the heart and lungs, while the hips protect a different set of organs. The vertebrae are extra special. How are bones connected? What is a muscle? What are the different types of joints and how do they work? Why do adults have fewer bones than children? What is the difference between a ligament and a tendon? What can kids do help maintain a healthy skeleton?

An extensive glossary and a learn-more section will aid in comprehension. Other aids within the book are a table of contents and excellent index. Reading activities are suggested by the text and on the publisher website ( Many teacher aids are also available through the website.

The photographs and drawings used are lively and attractive. Diagrams of bones and skeletal parts alternate with kids using their bones. For example, “Your lower jaw helps you bite into an apple,” and “You can sit cross-legged because two bones in each leg can twist.”
