Mrs. Bradley's Grade 2
During the past month in learning about polar bears, we have been hearing over and over that blubber is an excellent insulator. On Friday we got to see if blubber is as amazing as we keep hearing. We did a demonstration where one hand got put into snow and the other hand got put into a bag of blubber (actually shortening, blubber's a bit tricky to get in Calgary). Then we got to feel for ourselves if blubber was good at keeping animals warm. Students were surprised at the temperature difference between their bare hand and their hand that was insulated by the blubber. Now we know why polar bears can swim in the cold waters of the arctic!
