Explores the details of human and animal bones, comparing the differences between the skeletal structure of various species, with several gatefolds that display the skeletons of many creatures.
Explains why the skeletal system is important; explains how bones work, describing bones' sizes and shapes, joints, and bones' interaction with muscles; and provides guidance on keeping one's bones healthy.
Sally, Joe, and Ben learn lessons about animals and animal skeletons while on a visit to the museum. Includes pull-the-tab illustrations that show each animal as a skeleton and as it looks alive.
