What’s Blubber?
Posted by Ann PalmRecently in Art Class Kindergarteners made polar bears! Their artwork sparked an interest about these large mammals who live in the cold. How do they keep warm in the frigid waters of the Arctic? Blubber was the answer. But what is blubber and how does it work? Using Crisco as our blubber Kindergarten did and experiment. First they put their hands in ice water. Kindergarteners decided they could never swim in the frigid water. Next we took turns putting Crisco in a plastic bag until it was half full. Then we wrapped our hands in another plastic bag and into the Crisco to surround our hand with “blubber”. Last we took turns submerging our hands in the icy cold water again. To our surprise we did not feel the cold as we did with our bare hands. From this hands on experiment Kindergarten learned that this thick layer of fat provides insulation from cold ocean temperatures.
