Best Selling Books by Peter D Riley

This series introduces the first concepts that surround the physical sciences. The text combines statements and questions in such a way that it develops a child's understanding of science and the language related to it.

Forces and Movement looks at the different forces from gravity to friction and the effects they have on objects and their movement. The Earth and Space explores how the Earth moves around the Sun and its position in space as a whole. Both books consider how the ancient Greeks explained these phenomena and why the work of people like Newton and Galileo led their ideas to be reinterpreted.
