Two objects can be the same size, but not the same weight. Readers will learn not just about pounds and ounces, but also about how density, gravity, and mass affect weight. Using colorful photographs and illustrations of ancient and modern scales, this book will engage readers with fun facts about how boats float and how weight is used to make cookies. Using a range of familiar animals, including 7-ton elephants and 8-pound cats, readers will enjoy relatable examples and a concluding activity in which they can use their new knowledge.
