# Investigating Heat Loss In Animals.

Extracts from this document...

Introduction

Investigating Heat Loss in Animals. Aim: My aim is to, investigate how the body size of an animal affects the rate of heat loss. Prediction: I predict that as the smaller the animal/tube the longer it will take for the heat to be lost. This is because there is a larger SURFACE AREA; therefore it will have a smaller VOLUME and thus take longer for the heat to escape. Plan: I am going to be using four test tubes, which represent four animals. All of the test tubes will be different sizes to show the different size in animals. I will heat water to 37o as this is the normal temperature of a body and I will place the water in each test tube, I will be taking temperature readings every minute for ten minutes. ...read more.

Conclusion

Evaluation: Overall I came up with the results I expected to come up with, but this investigation could be improved by: Repeating it over and over to get ACCURATE results, Using different sizes of tubes, By investigating other factors that affect heat loss. I tried to keep the investigation a fair test but, I had to round the measurements up to the nearest mm or cm, the temperature readings have been read to the nearest integer; therefore not accurate. My graph shows proves my prediction as the VOLUME decreases the time taken for the heat to be lost does as well decrease. Again I could have done this investigatio several times to get morea ccurate results to find out WHAT affects the actual HEAT LOSS and I could also investigate different factors.

But we must still wear safety goggles and an apron to ensure our eyes remain out of harms way. I will repeat each experiment 3 times, then average these results and so plot them onto a graph. This will make the data more reliable and the chance of an anomalous result occurring will be significantly reduced.

Conduction is also improved if the molecules have free electrons, which is why metals are such good conductors. Insulation reduces conduction because it is a bad conductor of heat itself, and it traps layers of still air. Stationary air is a bad conductor of heat because air has particles that

In order to keep the other variables constant and to ensure the experiment as precise and reliable as possible the following will be done: 1. Measuring cylinders will be used to measure the exact amount of water. When measuring out the water the readings will be taken from the meniscus
