The Human Body

February 1, 2009
Gr 5-9-The workings of the human body are expertly summarized in 11 tidy chapters, which include experiments that explain how the body works by creating models that either imitate or test its functions. The chapter on the respiratory system describes how to build a working model of the heart's four chambers with circulating "blood," while the chapter on the senses demonstrates how to make optical illusions. Many of the activities require adult supervision due to the materials required. For example, the decalcifying bone experiment calls for hydrochloric acid. Other projects include making a fingerprinting kit, forming an exact model of one's teeth, and taking a DNA extraction from plant cells. Simple drawings and cartoons enliven and illuminate the text; however, the black-and-white format detracts from their potential power. The scientific explanations are superb. A great addition to any collection."Ragan O'Malley, Saint Ann's School, Brooklyn, NY"
