An understanding of science helps young people to answer questions about the world around them. The SCIENCE FUNDAMENTALS series provides an introduction to four important areas of science: Energy, Life, Space, and Time. Each of these 48-page books is written in an easy-to-understand style, and includes numerous color illustrations and maps. A chronology, glossary of terms, a guide to additional resources for more information, text-dependent questions and report ideas, and an index supplement the up-to-date information provided within the books.
