Gardner cleverly expands his science fair experiment books by encouraging readers to build their own weather station and musical instruments. Each volume includes facts about sound or weather and a collection of basic experiments, some of which require readers to build their own equipment and some of which work with more readily available materials. The narrative-a clumsy combination of science lesson and superhero adventure-is contrived, though Max does model scientific investigation in a way that captures some of its complexities. Short sentences on lefthand pages, usually one to three per spread, plus a "time fact" running across the bottom of the pages, use easy-toread vocabulary, with bright photographs on facing pages. Fire offers true tales of how horses were used to save lives before the advent of motorized equipment; Hollywood discusses the roles horses have played in the film industry, from the advent of silent pictures to modern cinema.
