Walrus Blubber!

Who knew blubber could be so much fun! Today we learned about the walrus.  We made an experiment to help the students understand how blubber keeps a walrus warm in the cold ocean waters they live in.
Super easy to do! 
 Fill a large zip-lock bag half way with butter then tape a smaller empty bag inside.  Fill the second large zip-lock bag half way with water then tape a smaller bag inside that one as well. Place both bags in a tray of ice cold water.  The students will be able to place their hands inside both bags to feel the temperature difference without making a mess.
