Gr 4--8--This title offers a terrific assortment of projects to make using household materials. The inventive projects will excite any budding builder. The text features detailed instructions, diagrams, and background information on inventors and engineering areas. The introduction provides material suggestions, such as types of glue and the pros and cons of the various types of cardboard. Six chapters highlight projects that include robotics and animatronics, audio and optical engineering, aeronautics and nautical engineering, mechanical engineering, and harnessing energy. Each chapter contains three to six different activities. The "Test and Tinker" text encourages redesign and emphasizes that the first time making a project might not be successful, but youngsters should reassess and try to problem-solve. STEAM activities, such as the ones featured throughout the text, foster creativity, problem-solving, and teach the value of repurposing items. The sample projects include a rocket blaster (DIY stomp rocket), cardboard roller coaster, periscope, robotic hand, and handmade spin art. VERDICT An engaging addition to any "How To" section.
