Exploring the World of Physics - From Simple Machines to Nuclear Energy (Paperback)

The latest installment of the wildly successful "Exploring" series, this textbook supplement explains physics in remarkable clear detail. Complemented with black-and-white illustrations, the book uses ordinary speech to explain the concepts of physics. The author's goal is to "write at a 6th grade level, but explain the concepts so that a motivated 4th grader can understand the material."
