★ “An excellent nonfiction resource for all libraries, this comes highly recommended."
—School Library Journal (starred review)

"Using very simple terms and aided by Raff's whimsical illustrations, Adler introduces young readers to the concepts of gravity, mass, weight, inertia, and resistance. Everyday examples and objects are used to illustrate the principles, such as a ball rolling off a table or marbles falling through water. Each of these examples or activities could easily be replicated by readers at home or in the classroom."
