Polar Animals

Science · Animals of the World · conceptual

Explore animals of the Arctic and Antarctic — polar bears, Arctic foxes, and walruses in the north; penguins, seals, and albatrosses in the south — and understand how polar animals survive extreme cold through thick fur or blubber, huddling behaviour, and seasonal changes like white winter coats

Sign in to track this

What mastery looks like

  • Names at least 3 animals each from the Arctic and Antarctic
  • Explains at least two adaptations for surviving cold (blubber, thick fur, huddling, white camouflage)
  • Knows polar bears live only in the Arctic and penguins only in the Antarctic/Southern Hemisphere

Check your understanding

If Polar Animals sees a nature programme about the Arctic, can they explain how polar bears stay warm in freezing temperatures and name at least two differences between Arctic animals (north) and Antarctic animals (south)?
