Pocket Genius: Science

Covering the basic principles of science, including matter and materials, energy and forces, and the living world, Pocket Genius: Science is a junior look at science, teaching young readers what things are made of, how things move, and how life works. Touching on biology, chemistry, physics, and more, Pocket Genius: Science answers questions such as Why do lemons taste sour? Where does electricity come from? How do plants make their own food? and more to help explain everyday science in our world.

Redesigned in paperback, DK’s best-selling Pocket Genius series is now available in an engaging compact and economical format that is ideal for both browsing and quick reference for use in school and at home.
