This week grade 4 was working on adaptations in science. Adaptations are things animals and plants develop to defend against predators, find food, and withstand heat and cold. An experiment we did was checking how animals in the Arctic withstand the cold. What we did was have a bucket of cold water then we stuck our hands in it for a little bit then took it out and put a plastic bag on our hands and stuck it in. It made me a little less cold but I was still feeling the cold. Finally, we put margarine (to represent fat) in the bag and put our hands in the water. I barely felt anything! Have you done any interesting experiments? If you have comment about them.
