Cold-Weather Adaptations

寒冷气候的适应性

Description

Understand how polar animals are adapted to survive extreme cold — blubber (thick fat layer) insulates seals and whales, hollow fur traps air for warmth in polar bears, counter-current heat exchange in penguin flippers prevents heat loss, Arctic foxes grow thick white winter coats for camouflage and warmth, and some animals migrate to avoid the harshest months

Mastery Evidence

✓ Describe at least three cold-weather adaptations: blubber, hollow fur, counter-current heat exchange, white winter coats, or migration
✓ Explain the purpose of each adaptation (e.g. blubber insulates against cold water, white fur provides camouflage in snow)
✓ Use the word adaptation correctly to mean a feature that helps an animal survive in its environment

Assessment Prompt

Can your child explain several ways polar animals survive the freezing cold — like a polar bear's hollow fur trapping warm air, a seal's thick blubber, or an Arctic fox changing colour in winter?
