In our small groups this week, we studied how polar animals stay warm. We learned that they have an extra layer of fat under their skin called blubber. We had a bowl of water filled with ice and talked about ice sinking or floating and how you can only see the top of the ice. This is just like icebergs. We then put our unprotected hands in the water to see how cold it was. Then we took turns putting our hand in a bag filled with shortening to simulate blubber. We found that the water wasn't very cold anymore! Here are some pictures to enjoy.
