Gr 4-6-Highly readable titles that contain a considerable amount of information. Hearing examines sound waves, how sound is measured, the outer and inner ears, and the brain and hearing. Smell details the structure of the nose, discusses the role of the brain in smelling, smell and taste, and scent memories. Taste covers taste buds and taste cells, taste and smell, "Supertasters," and other topics. The colorful, well-placed diagrams and photos with informative captions will help children understand the concepts presented. However, the placement of chapter headings is somewhat confusing. They are located at the top of odd-numbered pages even though chapters begin on even-numbered pages. Steve Parker's "The Human Body" series (Watts, 1989; o.p.) is comparable in content, but not as well written.
