A fun experiment book that allows kids to follow in the footsteps of famous scientists. Everyone's favorite science teacher returns with an exciting new book of projects that focuses on the people behind some of the most important science discoveries of all time. Janice VanCleave's Scientists Through the Ages introduces children to more than 25 scientists, such as Alhazan, Archimedes, and Galileo in physics; Henrietta Leavitt and Maria Mitchell in astronomy; Louis Pasteur and Antoine Lavoisier in chemistry; and Alexander Fleming and Rachel Carson in biology. Each experiment is based on a particular scientist's discoveries, and the book includes brief biographies of each scientist as well as descriptions of his or her work. As with all of Janice VanCleave's books, the science is easy to understand and each project can be done with everyday objects from around the house.
