Yet at no other time in this century has the level of science knowledge among elementary and high school students been so dismally low. Journalist James A. Haught, who created this book in response to queries from his four children as they were growing up, presents 100 basic science questions and provides simple answers with clear illustrations. These and many more questions are addressed in a breezy style that conveys broad, basic scientific ideas in the fastest, easiest form possible.
