Chemical processes have always been a part of life. They enable our bodies to function and are the basis of countless substances and processes we take for granted. This intriguing book explores the world's natural chemistry and how we understand and exploit it. From the first use of fire, people have practiced chemistry to produce food and drink, tan leather, make dyes for clothes and cosmetics, work metals, and produce glass and pottery. Today, chemicals help to purify our water, improve agriculture, and manufacture drugs, synthetic fabrics, and plastics. Our growing knowledge of the Earth's elements, the properties of atoms and DNA, and how substances interact, has resulted in many new technologies, products, and scientific advances.

Focusing on contemporary and historical developments in the study of human anatomy, Eyewitness: Human Body features clear, age appropriate text, photographs, charts, graphics, and 3-D models highlighting the inner workings of our bodies — from the framework of our skeleton to the millions of tiny cells that make our bodies work. In this updated edition, kids can discover how muscles and joints help us move, find out how x-rays work, see the network of nerves inside the human head and more in a format that makes complex scientific concepts easy to understand.
