This ready reference presents fascinating facts about 100 amazing inventions, a panoramic overview of the history of science, and a collection of engaging reads. Inventions are the stuff of dreams, quickly gaining widespread use, becoming central to culture, and ultimately changing our lives. They teach us a great deal about creativity and scientific principles, and, of course, the power of invention is of utmost importance in today's world of technology and innovation. Focusing on the 100 most significant scientific inventions of all time, this ready reference presents fascinating facts about amazing inventions, a panoramic overview of the history of science, an introduction to some of the most important inventors in history, and a collection of engaging reads. Each entry, arranged chronologically according to when the invention was made, contains information on what the invention is, who the inventor was, and how the invention was created. It also provides the historical context of the invention, its significance today, and information on resources for further reading/research. More than two millennia's worth of inventions are covered, ranging from the practical (clock, eyeglasses) to the everyday (measuring spoons, ball point pen), the life-saving (antiseptic, chemotherapy), and the mind-boggling (the number zero, cloning). By covering inventions throughout history, rather than just the 20th and 21st centuries, and presenting information comprehensible to young readers, this book fills a gap in the literature. It is a wonderful resource for student research and reports; can easily be used for read-alouds or as an introduction to teaching units on inventions; as well as a solid general reference on inventors and inventions. Grades 4-9 (adaptable to other levels).
