Children's LiteratureAs part of the series "Human Body," this book provides an introduction to the different kinds of muscles and what they are needed for. This would be a useful teaching aid for young children beginning to learn about individual structures of the human body. The captions for each photo appropriately summarize each brief chapter, and the photos are rich in explanation. Brief and basic analogies are used throughout the text to reinforce points made about the importance of the muscle's functions. The activity at the end provides a hands-on experience for kids. 2004 (orig. 1978), Smart Apple Media, Ages 7 to 9.
