Gr 3-5--This series will be useful in any collection needing updated texts about the human body. The titles clearly explain what functions each of the six systems performs. The design is eye-catching and attractive, with lots of clean white space and an easy-on-the-eyes font. Captioned photographs or colorful diagrams appear on every page. Many of the photographs were taken with a microscope and are sure to fascinate children. In every volume, the detailed photo captions and sidebars provide additional interesting factoids that complement the main texts. For example, readers learn in Respiratory that "You can sing high and low by tightening your vocal cords." These titles will appeal to browsers, and the strong back matter makes them useful for reports as well.[Page 30]. (c) Copyright 2012.
