To find the relationship between surface area to volume ratio and how this effects heat loss

Extracts from this document...

Introduction

David O'Sullivan 11S October 2. 2001 Planning Introduction In this experiment my aim is to find the relationship between surface area to volume ratio and how this effects heat loss, and how animals adapt to surrounding temperature. The two variables in this experiment are the surface area to volume ratio, and the rate of heat loss there is. This effects where animals live, because if you had a small animal living in the North Pole it would loose more heat because of the smaller surface area to volume ratio. It would be different for a polar bear living in the Poles because it has a much bigger surface area to volume ration, therefore keeping in more hear. Aim Our aim is to find out the surface area to volume ration effects on animals heat loss in real life. As we are unable to use animals to carry out the experiment we have to use the best models of animals we have, which is test tubes. ...read more.

Conclusion

All of my results followed a certain pattern; they lost heat according to the size of the test tube, the bigger the test tube the less heat lost and the smaller the test tube the more heat lost. My proposed method worked for the experiment. I followed my instructions in my method closely and I think that overall my experiment was successful. The results were almost accurate, there was a few odd results. The reasons for this could be that we were sometimes a few seconds late reading the thermometer. There were few problems faced during this experiment, the main problem was the fact we had tinfoil over the top of the tube, and to make the reading we had to move the thermometer up therefore causing the temprature to rise (heat rises). If I had the option to repeat the experiment I would probably use more sized test tubes to get more accurate results table. I would also complete the experiment on the same day, to reduce the chance of room temprature changing. ...read more.

    I gathered many results and averaged them, then checked them again but the results weren't what I expected. I plotted the results onto a graph. As you can see the results aren't very decisive. My explanation was that the container in which the water was held wasn't large enough.
