How do polar bears stay warm?

Our prediction: 

The thick layer of blubber (fat) under their black skin helps keep them warm.

Our Method:

We timed ourselves to see how long we could keep our hand in a bowl of iced water. Mr Whitney then covered our hand with blubber (lard) and we timed ourselves again.

Results:

Merryn49sec53sec

Conclusion:

The blubber helps keep our hands warm for a longer time in the cold water. So we think our prediction is right, blubber helps keep polar bears warm!
