WALT discuss how blubber helps to keep Antarctic sea mammals warm.

Room 4 recently had an 'Antarctica snow day' where we explored, discussed and took part in activities related to the southern most continent and its sea creatures. We set up a science experiment to find out how blubber keeps marine mammals warm in the cold waters of Antarctica.

First, we put our hands into some icy cold water to see what it would feel like.

Next, we used the 'blubber bag', or a double layered bag with vegetable shortening in between, like a glove when we put our hands in the water.

We found that it was much less cold to put our hands in with the 'blubber bag' and we hardly even felt the water at all!
