Thoroughly updated to cover new technological advances from the Internet to the Mars expedition, a profusely illustrated, colorful encyclopedia explains more than two thousand scientific subjects in a lively way geared to children.
This encyclopedia can make anyone feel like a scientist! Not only does it have fascinating facts on everything from atoms to zephyrs, it also shows how scientists work--describing, measuring, and asking questions about the world. Filled with detailed, sharp illustrations and eye-catching photographs, this book could keep a curious kid (or adult!) occupied for weeks. The one- and two-page entries are thematically organized--much more useful than alphabetical entries for making connections and thinking about whole systems. Some of the best categories are "Reactions," "Materials," "Weather," "Space," and "How Living Things Work." But every entry has accurate, well-written text cross-indexed to related pages and to the "Fact Finder" section in the back, with charts, tables, and maps to use with each section. A glossary and index round out this thorough package.
