Children's LiteratureThis soft-cover volume gives a "lode" of fascinating information about metals, from ancient days of early civilizations—who first used them to craft crude tools and weapons—to modern times, when advanced metal technology enables us to explore outer space and the depths of our own oceans. Along with a brief history of metallurgy, the book covers a host of other topics: the physical properties of metals; how metals are mined from ore deposits in rock; where in the world various types of metal ore deposits are found and how geologists find them; the ways in which pure metal is processed to separate it from the ore in which it's found; and the importance of recycling—just to name a few! Richly illustrated with full-color photographs, diagrams and drawing. Interesting tidbits of information are given in sidebars and captions. Includes glossary and subject index at the back of the book. Kids will be eager to "dig in" and learn! This book is part of the "Rocks, Minerals, and Resources" series from Crabtree Publishing Company. 2005, Crabtree Publishing Company, and Ages 8 to 10.
