Reflection

I really enjoyed this experiment, and I learnt a lot from it. I had a lot of fun during this experiment, and sadly, this brings an end to my science fair. I'd like to thank everybody who helped and encouraged me during this experiment, especially my family and my teacher, Miss Callaghan.

Application - Why is this experiment important?

This experiment is very important for our everyday life, as we wear clothing everyday to adjust to the surrounding temperature. This can also be useful to future materials used to make clothing and uniforms. Also, this experiment is important if you are out in the rain, or if you fall overboard from a boat, because this experiment shows you how warm different clothing materials will keep you when you are wet.

My Conclusion

The experiment has proved the hypothesis correct, as the dry wool proved to keep you the warmest in all 3 tests. The materials that followed is in the following order: dry polyester, dry cotton, wet wool, wet polyester, wet cotton, and lastly, the control. If I had more time to do this experiment, I would like to test an even wider range of materials.

Observations

From the experiments, I observed that the temperature decreased the fastest in the first 20 minutes. The temperature then decreased slower between 20 minutes and 60 minutes.

Graph

Here is the graph of the averages of the temperatures:

Results

I have finally finished testing, and I won't bore you with all the tables. Instead, here is just a table with all the averages of the materials.
