Description

Why did the brown bear evolve into the polar bear? Animation describing how brown bears adapted to life in the Arctic. Sam, a young tortoise, is hungry. Grandad Charlie tells him a story about how brown bears had to travel a long distance to find food. A group of brown bears went to a region which was cold and inhabited by seals living on ice. The bears were hungry but their paws weren't good for walking on snow and ice, their fur wasn't thick enough for the cold conditions and the seals could easily see them coming with their brown fur. After a long, long time, some bears were born with bigger, thicker paws and with warmer, lighter-coloured fur. These were the bears which flourished. They are now called polar bears.

Classroom Ideas

When looking at variation, pupils could be challenged to identify the similarities and differences between the brown bear and the polar bear. The children could use the clip to write simple stories on the journey of the brown bear. This clip could also initiate a discussion by asking children what might happen if the brown bears went on holiday to the polar regions and the polar bear went on holiday to the forests.
