100 Scientists Who Made History

Gr 4–7—In typical DK style, an engaging biography collection is presented. Types of science or scientific ideas are used to categorize those profiled: pioneers, biologists, chemists, physicists, and innovators. The subjects are further arranged chronologically, from ancient times through present day, within their specific category. Throughout, readers will encounter both well-known and lesser-known scientists from a variety of countries. Each spread provides brief historical background, biographical information, descriptions of the accomplishments, and the results of these discoveries. Pages are rich with images, primary sources, and models that offer readers context for the scientists' time period and specific interests. An enjoyable read for children who respond well to brief entries while being cohesive enough for readers of longer books. However, the format and placement of features on the spreads could be potentially confusing to struggling readers.
