极地动物

探索北极和南极的动物——北极有北极熊、北极狐和海象，南极有企鹅、海豹和信天翁——并了解极地动物如何通过厚厚的皮毛或脂肪、挤在一起取暖，以及像冬天换上白色毛皮外套这样的季节性变化来抵御严寒。

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

评估问题 / Assessment

如果{{name}}看一档关于北极的自然节目，他们能解释北极熊如何在严寒中保持温暖，并说出至少两个北极动物（北方）与南极动物（南方）之间的不同吗？

If {{name}} 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)?
