This richly illustrated reference guide is more a condensed, advanced high school course in physics, chemistry and biology than a traditional dictionary. Each topic - listed by subject and not alphabetically - is explored through colorful, detailed charts, graphs and tables; cross-referencing links the major branches of the natural sciences. Middle school-aged children may not be ready for such an extensive, sophisticated text, but high school students will find the straightforward definitions and comprehensive index essential study companions. A 2000 Parents' Choice® Recommended winner.
