Even if objects are about the same size, that doesn't mean they're the same weight. Readers will learn about many units that measure weight and about concepts such as density, gravity, and mass. With colorful photographs and engaging illustrations of ancient and modern scales, this book will help readers learn facts about weight, including how boats float and how weight is a factor in baking.
