To complete this investigation I purchased a large tub of Crisco from the grocery store. I filled a large sandwich Ziplock baggie about 3/4 of the way with Crisco and then inserted another baggie into the full bag. This created a “blubber mitten” for my students. Before the experiment I placed a basin of water in the freezer for about 40 minutes and then added 3 trays of ice cubes to the water. (I wanted it to be VERY, VERY cold!)
My class and I discussed how cold we thought the ocean is in the Arctic. (28.8* F in case you were wondering!) They took turns dipping their hands in the basin of FREEZING cold water and then took turns using the blubber bags.
They were VERY surprised at how toasty warm their hands were in the blubber bags! In fact, after our group “experiment” my students wanted to time themselves during exploration centers to see how long they could withstand the water without the blubber mitten and then with the gloves!
Our next Arctic activity was a STEM activity!
