How do animals keep warm in freezing conditions?
Today we did an experiment based on how animals keep warm in freezing conditions. The animals of the Arctic and Antarctic circles spend their lives surviving subfreezing air temperatures and frigid water. Their secret is blubber, a thick layer of body fat that comprises up to 50% of some marine mammals. We tested this theory out today using lard and ice cold water. It was a lot of fun!! We also discussed how to ensure it was a fair test.
