How Polar Bears Stay Warm

Yesterday we did a cool experiment in showing the kids how the Polar Bears stay warm in the cold. We filled a glove with lard [fat], then had the kids put a glove on and slide their hands in the glove with the lard [fat]. Then, we had them place their hands in cold water and tell us which one felt colder then the other. They had a lot of fun with this and so did we!
