We are learning about the tundra biome this week so we did an experiment to find out why animals in this habitat have lots of fat on their bodies.
Basically we had some iced water in a bowl. We placed 2 bags inside, one filled with fat (vegetable shortening) and the other empty. We then stuck our hands into the 2 bags and compared how it felt. The one with the fat was warmer. We also stuck in a thermometer to be more scientific.
