This short video from Nat Geo is a really nice introduction video that can be used to start a lesson on arctic life, bear/mammal study, ocean mammals, food chains and webs and a wonderful opportunity to get started on examples of how are human behavior can have an impact on life around the whole planet. This video does not offer an activity, but the introduction of ideas that others are working on can be inspirational for you student to see what ways they might want to help polar bears or the planet in general. Polar bear facts and saving the world, this video is cool.
