Investigation: Body temperature regulation

Guiding question:

To what point does fur determine an arctic foxes wellbeing in the wild and how much protection against extreme temperatures does it really offer.


In this experiment I will be attempting to justify my findings that I have gathered over the course of a few different experiments. What I have been gathering information over is the suitability of an arctic foxes fur coat. I have gone about finding this out by simulating a model of an arctic foxes fur coat through many trying and stressful conditions. The way I did so was by firstly dividing the experiments into three different steps.

The first step entailed me attempting to put my model arctic fox in sub zero temperatures, as it would be in real life. What I did however was to put two models in the fridge. The first was a simple test tube covered with cotton, while the second had a space of cool air between the fur and the test tube simulating the space that would be created when a fox puffs out its fur almost like when we get goose pimples.

The second experiment was designed to signal whether it changes anything to the temperature of my two test tubes if there is wind or not. I also did that same experiment of wind with my test tubes both drenched with water, again this would simulate a real life situation such as rain and wind or even snow and wind.

Lastly I decided to put my test tubes (or arctic foxes!) at normal room temperature to determine how much the tests really did influence the temperatures, in this way I could see what exactly was going on in terms of the cooling curve.


I expect the following experiment to give me a rough enough idea of arctic foxes protective measures and to help me better understand the full extent of their heat retaining abilities. I expect that my experiment has a great deal of flaws yet I also believe that there will be enough raw data to accurately determine a positive...
