Gr 2–5—Having a hard time convincing sports lovers that STEM includes them? Then look no further—these titles cover bikes, boats, balls, and balance beams. The text asks questions to draw readers in and provides details about the science behind the equipment, uniforms, and techniques for the various Olympic events. Full-color photos give each spread visual appeal, and "Did You Know?" text boxes add details to the main discussion. "Take a Look!" insets feature diagrams that show things such as the forces acting on a swimmer or how gymnasts use kinetic energy. Each book ends with an activity that encourages readers to experiment with one of the topics, such as how friction affects the bounce of a tennis ball. General ideas for parents and teachers are included in the series, as well as access to FactSurfer.com for recommended websites for further study. VERDICT A solid series for intermediate grade science or sports fans.
