The children came across the word “blubber”
During our work on Arctic animals we carried out an experiment to see how a seal’s blubber can protect it from the icy Arctic seas.
We first explored how long we could keep our hand in ice cold water – which was not long at all!
Then we used plastic bags to simulate the animal skins and lard to be blubber and tested again how long we could keep our hands in the water.
The children were amazed that they could no longer feel the coldness at all! We found that the icy water didn’t feel quite so cold when our hand was surrounded by a layer of fat.
