Fifth-grade students conducted a science experiment to determine the most effective adaptation of insulation for animals in the Arctic. They compared human skin, aluminum foil (fish scales), marbles (turtle shells), and Crisco (blubber) by placing a hand inside a bag filled with an insulator and then into buckets of icy cold water. After making observations through repeated trials, the students concluded that blubber was the most effective adaptation for warmth, with aluminum foil coming in second place!
