Investigating heat loss from huddling penguins
In my investigation, the one thing that I shall change by equal amount each time is the position of the test tube been assessed. (The position in a huddle)
In my investigation, the thing I shall measure, will be the temperature.
The make the investigation a fair test, here is a list of things that I'm going to keep the same:
* Test tubes sizes
* Amount of water in the test tubes
* Time at which we start the clock
* Starting time
Apparatus - here is a list of everything I shall need to do my investigation:
* Test tubes (penguins)
* Hot water
* Thermometer
* Water heater
* Stop watch
* Beakers
* Elastic band
* Goggles
* Kettle
My prediction - what I think will happen:
I think that the difference in position will affect the temperature. Therefore I think that the penguin positioned in the middle will have the greatest temperature all the way threw the experiment.
Why I think this will happen:
A penguin will lose heat in 3 different ways. One, by conduction - where heat moves threw a solid by the particles vibrating (creating the knock on effect). Two, by convection - this is where hot air/particles rises and cold air/particles rush to take its place causing convection currents. And three, by radiation. Radiation can travel through empty space and needs no form of median.
