Crunch! Massive white paws step across the frozen sea ice without making a sound. A black nose lifts to the wind. It's a polar bear, and it just smelled a seal hiding under three feet of snow. Most kids know polar bears are big. But the animal in this book is unlike anything they have imagined. It can swim 426 miles without stopping, sprint 25 miles per hour across ice, and survive eight months without a single meal by living off stored fat while raising tiny cubs in a snow den. "The Nature Kid's Guide to Polar Bears" takes children ages 7–12 deep into the frozen Arctic, where the sun disappears for months at a time and the sea ice shifts like a living puzzle. Written for Level 2 readers in short, confidence-building sentences, this book covers everything from the two-layered fur that sheds water like oil, to the razor-sharp patience of a bear standing motionless for hours over a breathing hole, to the mother who loses half her body weight keeping her cubs alive through the long polar winter. The undisputed king of the Arctic, with a story as wild as the ice it walks on. Your child will discover that polar bear fur is actually clear and hollow, not white, that their paws work like snow shoes and football cleats at the same time, and that newborn cubs weigh no more than a guinea pig. These are remarkable animals facing a rapidly changing world, and understanding them is the first step toward caring about their future. Thousands of young readers have explored the Nature Kid's Guide series. This giant of the frozen north is ready to be their next favorite.
