During our unit on polar regions, we learned that some arctic animals survive such cold temperatures by having a layer of blubber surrounding their bodies. The blubber protects them from the cold and icy water. We filled a glove with shortening (to simulate blubber), and placed our gloved hands inside. We then placed our gloved hands and bare hands in icy water. We learned that the “blubber” kept our hands toasty warm, while our bare hands got very cold!
