"Do bears sleep all winter? Some do. These bears settle down for a long, long sleep. It lasts all through the cold winter months." In this wonderful introduction to bears, kids will find out that bears mostly live by themselves, that brown bears are the largest variety, weighing in at about 1 ton, and that people used to worship bears! The Bergers explain basic science concepts, like hibernation and molting, in a way that's accesible to kids, while keeping them enthusiastic about learning with questions like "When do bears attack?" and "When did the first bears appear on Earth?"
