Gr 2-4--These informal titles detail various bodily functions in people and animals. Activities related to exploring the workings of the human body are embedded throughout the texts as well as in a designated "Activities" section. Information is attractively displayed; the brightly colored layout is visually interesting and includes a mix of photographic images and computer-generated cartoons and diagrams. Changes in font style often accompany information about related animals, although inconsistently, which can be distracting. The author's inclusion of a letter describing her research process is a nice touch; the letters in It's Spit-acular! and Pump It Up! are the only ones to include bibliographic information on her sources. Students craving explanations of the human body's processes, with a nod toward the disgusting, will enjoy these books. With the exception of It's Spit-acular!, which contains rarely covered information, these are additional purchases.--Nicole Waskie, Chenango Forks Elementary, Binghamton, NY[Page 103].
