Eye-catching visuals and effective graphic design pack lots of information about body parts and systems into a few pages. Three or four activities interspersed among the factual presentations reinforce the concepts presented. Most volumes include at least one activity that produces a “model” . . . . A plethora of diagrams plus detailed drawings and close-up photos help explain complex structures and functions of body parts. . . . Well-designed and informative presentations for young readers to explore on their own and investigate further with adult help, as noted above.
