New Mexico, northwestern corner. Here, amidst the greasewood bushes and clouds of dry, sandy soil, are the silent ruins of colossal mud and wooden houses, a mysterious remnant of an ancient civilization. In Chaco Canyon, readers learn about the discovery of these amazing structures and follow generations of archaeologists as they uncover the secrets of the canyon''s past. A veritable early Native American detective story, the book includes numerous sidebars on archaeological techniques, timelines, related sites, photographs and illustrations of the sites and artifacts, and a fascinating interview with archaeologist Gwinn Vivian who grew up in the canyon. Series copy: Buried treasure, high adventure, lost civilizations--Join archaeologists as they dig for the past at exciting sites around the world. From the first excitement of the original find to the excavation and scientific breakthrough, these richly illustrated books team professional archaeologists with established science writers to bring the fascinating world of the archaeological process to life.

What kind of insect would make its home in a pile of dung? Does a female praying mantis really eat its mate? Do house flies spit on your food? Author Margaret J. Anderson answers all of these questions in this book as she explores the weird behavior, habits, and characteristics of insects. There are millions of different kinds of insects in the world, and many of them do things so bizarre you''ll have to read it to believe it.

Aristotle is one of the most significant figures in all of human history. Over the course of his life, he studied and wrote about every possible field of knowledge. He studied physics, zoology, botany, and chemistry before any of these fields of science even had names. Without the benefit of modern tools like the telescope or microscope, Aristotle still laid the foundation for nearly all later developments in Western science. In addition to his work in science, Aristotle contributed a great deal to our ideas about art, literature, ethics, and theology. Aristotle''s influence is so deep, in fact, that many of his ideas have been absorbed into the very language of science and philosophy.

How can we organize and name all of the different animals and plants in the world? Many had tried before, but Carl Linnaeus came up with a system that we still use today. This Swedish scientist from over 300 years ago is known as the father of classification. Linnaeus’s system gave each plant or animal just two names. For example, the scientific term for human beings is Homo sapiens. In Latin, Homo means "man" and sapiens means "wise."

Charles Darwin published his most important book in 1859 called THE ORIGIN OF SPECIES. In this book Darwin claimed that plants and animals living today are descended from similar species that lived long ago. It caused an immediate uproar and upset some people because it appeared to go against the Bible. The genius of Charles Darwin is his discovery of a unifying theory of biology, explaining the diversity of life.

Isaac Newton is best known for his theories of motion and gravitation. These laws served as the foundation of science for the past three hundred years. In addition, using a prism, Newton first discovered the that sunlight is actually made up of light rays of many different colors. Among his other discoveries is the branch of mathematics called calculus.
