(4) YA Secrets of the Universe series. The five volumes in this series clearly explain complex subjects in well-organized texts. Simple experiments reinforce the explanations, but because the lists of materials and procedures are embedded in the text, readers can't easily isolate them. Illustrations aren't always accurate in details. Each volume appends a time line that includes nonscientific items for context, and short biographies of appropriate scientists. Bib., glos., ind. [Review covers these Secrets of the Universe titles: Liquids and Gases, Matter and energy, Objects in Motion, Relativity and Quantum Mechanics, Waves.]
