Gr 8 Up—Tracing the evolution of six theories from their origins until present day, this well-researched series is packed with information that offers students a better understanding of the nature of science. Rich historical examples from key figures, many accompanied by quotes, illustrate the thinking behind the science while demonstrating the impact on both the discipline and society. Text-heavy, the books contain minimal images, but the ones that are present do their job well by illustrating, supporting, and making clear the material around them. Bright red "Words in Context" sidebars bring the glossary to the reader, flanking the text in which the vocabulary appears; unlike in similar titles, the in-text word does not appear in bold print. Source notes and a list of important people in the history of their fields are provided near the back of each volume, offering a wealth of resources should students choose to pursue further research. VERDICT A first-purchase consideration.
