Tin Can animal

Extracts from this document...

Introduction

Tin Can animal In this experiment we are testing to see how can animals cut down on heat loss? There are numerous things that animals can do to lower the rate that they lose body heat. They can have less surface area, they can also have different behavioural patterns, for example they can migrate, hibernate huddle in large groups and they can also hibernate. However I am not looking at any of these. The variable that I am looking at that is the one that is most common between animals that can lose heat. This is fur or blubber, animals usually have fur or blubber or both. When animals with fur become cold they raise their fur on themselves, to create a layer of trapped air to keep themselves warm from the harsh cold world. To see how affective this is. I am going to test it in controlled conditions. To do this in a laboratory environment, I am going to rap some fur around a tin can (the tin will model the animal). ...read more.

I also have to careful not to let the thermometer touch the can itself. Otherwise it will read the temperature of the can instead of the internal heat. Also to simulate the animal more realistically I am going to put polystyrene on the top and bottom, of the can representing fur on the feet and head. This will reduce the area exposed to the cold. I also have done this to make it safer for me to do the experiment. To make the experiment safer, I have also worn safety glasses all the way through the experiments and used gloves to handle the hot cans. I have taken my results over three lessons, so I am able to save myself time. I have taken temperature reading in ten minutes. So I am able to see a difference in the temperature from my data. This may not be as accurate as taking it in the next minute, however this would be a waste of time because I wouldn't be able to distinguish a difference between my results. ...read more.

Conclusion

Here you can obviously see the energy that has been saved and the energy that could have been lost if animals didn't have ether fur or blubber. Now to show that my theory only works up to this point I shall now draw a graph, which will further, conclude that my theory was correct. As you can see the energy loss should continue to become smaller and smaller as you continue to increase the layers of fur, and so concludes my successful experiment that my prediction was correct, and well backed up by scientific evidence. So in conclusion I have proven that fur is a good source of insulation, and that animals need some sort of insulation to retain heat energy which otherwise would have been lost. I would of liked to extend my research into this however sadly I have run out of time. I could, have looked into the surface area of animals or the difference of energy loss between homoeothermic and poiciothermic animals. There where endless possibilities to what could affect the energy loss of an animal but sadly there was not endless time of which I could use. ...read more.

    This is to ensure that as much heat energy as possible heats the water to ensure our experiment is as fair as possible. DISTANCE OF COPPER CALORIMETER- We must keep the distance of the copper calorimeter from the spirit burner the same after each experiment.

    very same energy hits the shiny surface and reflects back inside the beaker. This means that radiation is reduced. Conduction Conduction is the final heat transfer in which a substance transfers heat energy to another substance by direct contact of atoms or molecules.
