Today we talked about the differences between the Arctic and Antarctica; the weather differences and what animals live in each area. We also discussed how these animals keep warm. How marine animals use blubber to keep warm and how land animals use fur or how each uses a combination. We also did an experiment to see if blubber is buoyant and if it can help animals stay buoyant by putting rocks into bags of vegetable shortening to see if the rocks still sank. We also looked at fur and how animals have guard hairs and an under fur and what each is for. If your child came home with some fur, it is from a mink coat someone was throwing away that I thought the kids would enjoy having.
