Kevlar, blue jeans, airplanes--all of these are famous inventions founded in America. From a chemist in a research lab to a gym teacher in Massachusetts, this book takes middle-grade readers back in time to learn about the origins of each invention. Readers explore how these items or ideas were created or discovered and the impact they had on not only American life, but the lives of people around the world as well.
Compelling historical photos, stat boxes, and sidebars bring the stories to life, while "Think About It" sidebars offer critical thinking practice and strengthen reading comprehension. Includes a table of contents, glossary, index, and extra research sources.
