Many of the straightforward yet tricky questions children and young teens pose are addressed right here. This browsable compendium is divided into 5 chapters of approximately 30 pages each—Earth and Space, Prehistoric Life, Life, Science and Technology, and History—with each chapter containing 12 to 15 ordinary questions on a bold, busy, and colorful two-page spread. Each of these spreads contains specialized information; bright, action-filled backgrounds dominated by schemata or paintings; and intricate diagrams and text boxes wherever appropriate. The information is detailed yet rarely overwhelming. As an added bonus, the author has included a list of websites and books for further information at the end of each chapter, which offers ease of use for readers who wish to explore a specific topic in more depth. A superb book to have on hand when a student asks a question beginning, “Why does . . . ?” Grades 4-8. --J. B. Petty
