Gr 5–8—Scientific theories and laws are thoroughly defined and put into context with plenty of background and historical knowledge. Readers will find enough information to appreciate the many scientific advances that we enjoy today and see the potential for future progress. These titles are not only written and organized well, but they are also gorgeous in design. Full-color photographs and illustrations are set over colorful backgrounds that add depth but not distraction. Each title includes thought-provoking quotes from famous authors and scientists and some eyebrow-raising “Quick Facts” throughout.
