Polar Bears are the largest members of the bear family. Males can stand up to 10 feet tall, and can weigh more than 1,000 pounds. Despite their massive size, polar bears are also very good swimmers and can swim at a speed of 6 miles per hour, and can dive as deep as 15 feet. Polar Bears delivers an in-depth look at these amazing animals, while remaining accessible to children. Perfect for older kids seeking information for report writing, and as an introduction to wildlife for new readers. Children love the Our Wild World series because it's fun to learn about interesting animals. Each book in the series includes Fun Facts, 30 full-colour photos and illustrations, and a helpful list of Internet sites with more information.
