Eyewitness: Technology
Grade 4-6?In typical "Eyewitness" fashion, these titles explore two areas of science through clear, full-color photographs and lots of concise, well-organized text. Technology deals with how the development of machines and materials has affected the areas of communication, farming, medicine, and more. Endoscopes, food mixers, fax machines, and robots are presented, as well as everyday items like the BicTM pen and the hollow tennis racquet. Medicine travels from ancient times to the future, addressing alternative treatments, modern drugs, fads in health care, diagnostic techniques, etc. What really stands out are the numerous examples of tools of the trade, like the 18th-century brass enema syringe and the 20th-century electronic hand. Both volumes feature lots of white space, great photography, and clear explanations of terms.?Christine A.
