blubber science experiment

This week's science unit has been about pinnipeds; walruses, seals, sea lions, manatees and dugongs.
We did a science experiment to discover how blubber works to keep the mammals warm.
First, we put two gloves, one on top of the other onto one hand  and then put a glove covered with Vaseline on the 2nd hand.  We then covered the Vaseline hand with a second glove.  We put both of our hands in ice cold water and timed how long we could hold them under water before it got too cold.   Boo was able to hold her hand with blubber for a full minute longer than the "skin" glove and LE held the blubber hand twice as long as her first hand.
