Gr 4-6--These titles are organized by questions that introduce the body system, its function, and its care, but the questions are not stimulating. A final spread reviews the topic. Some subtitles don't accurately reflect the content. Why Do I Burp barely covers diet, while How Do My Muscles Get Strong is mostly on exercise. In Why Do I Have Periods, the photo choices put a depressing spin on menstruation. Though the large illustrations, photographs, micrographs, and insets including "Practical Advice," "Extreme Facts," and "Science Behind the Myth" add variety, minor problems mar the illustrations in several titles. For example, one in Asthma Attack shows the heart on the wrong side of the body, and in Pulse, a doctor shown with a patient is not using a stethoscope as the caption states.[Page 118].
