Editorial Reviews

Children's Literature - Chelsea Couillard-Smith
Early elementary school students compare marshmallows to chairs in this accessible introduction to "heavy" and "light." With large print, simple text and short sentences, Hughes begins by introducing "matter" and "mass." Vocabulary words in bold are immediately defined in the sentences that follow, eliminating the need to consult an appended list of terms. "Heavy" and "light" are described as "properties" of matter, and easily relatable examples illustrate the concepts, such as a bulldozer versus a coin and an elephant versus a goldfish. Classroom-friendly questions appear occasionally, challenging students to provide their own examples of objects that possess these properties. Photographs of a diverse cast of kids interacting with various objects as well as stock photos of items mentioned appropriately complement the text. In general, Hughes' language and examples effectively illuminate the ideas presented, and each chapter flows easily and logically to the next. The section on using a scale doesn't entirely succeed, however, referencing the "number" that states how much an object weighs, but excluding any mention of pounds or other units of measurement. Additionally, Hughes defines a balance as a tool "that tells us how much matter is in an object," a vague description that could benefit from an explanation of comparisons and relative weight. Overall, this entry in the "What's the Matter?" nonfiction series would be an excellent first introduction to basic physics for most elementary school classrooms, both as an instructional tool and a book for beginning readers to tackle independently. An index lists vocabulary words and the pages on which they appear, and a final note for adults provides an outline for classroom use.
