Investigate whether the huddling behaviour of the emperor penguins helps to conserve heat?

Introduction

Leanne Jones R11 Task: Investigate in to whether the huddling behaviour of the emperor penguins helps to conserve heat? Introduction/ background I am going to investigate if penguins huddling together help them keep the body temperature up. As the emperor penguins have small feet, wings, head and a relatively small surface area great for conserving heat, they also have a thick layer of fat underneath their skin for insulation also their feather helps to insulate, they are also are warm blooded. All these are great for the cold conditions that are in the Antarctic. Penguins have to survive extreme conditions the temperature in the Antarctica; the temperature has been down to -88.3 �C, but is normally below are round about -40. The wind has also been as fast as 200 mph. When a penguin breed it goes about 180 mile in to the Antarctica ice where there is less precipitation and the weather condition are less extreme. So with all the ways in which the penguins are adapted to live in the weather condition it. They still go to some where with less extreme conditions as the males will spend a lot of time standing in a huddle.[LJJ1] The heat will be transferred by radiation; Radiation is electromagnetic energy given off by all objects, which are above the temperature of 0 �C. ...read more.

I think this is because I could only measure as accurate to a half a degree. And also I have averaged all the results so that could be why the results are the same twice is three times. There are also some results that are out from the line of best fit. This could be for the same reason as before. The averages are strange of one of the results from the first results are out. On my graph I have also circled some results that are odd (have drop temperature a lot) this could be fore the same reason as before or I could be because I have read the thermometer wrong. All my result could be a bit out as I took the temperature off all the test tubes so I had to average all of those out and then average the results again because I repeated all the experiment 3 times. From my graph all of the lines of best fit are curved and the gradient at the top is greater than the gradient at the bottom; so the temperature went down slower the cooler the water was. ...read more.

  1. Why do penguins huddle to keep warm?

    submerge the test tube arrangement into it until they are all fill. I shall do this as it will assure that all the test tubes start off at 70 degrees unlike if I were to pour water into each individual test tube.

  2. Specific Heat Capacity

    Control variables: 1. Boiling temperature This is used in my final calculations and it is the boiling water that gives the kinetic energy to the metal therfore any significant diffences could result in not enough energy being transferred to the metal.
