Finding Out Why Penguins Huddle Up

Finding Out Why Penguins Huddle Up

Aim:

The aim of this experiment is to find out if when penguins "huddle up"

it creates warmth for the penguins.

Method:

In this experiment I am going to use test tubes to symbolise penguins

"huddling up". I will firstly get all of my equipment, then I will

fill firstly one test tube with water, then 9, then 17, then 25 in

bunches. I will fill them all with water at a temperature of 65

degrees C. I will leave each set for 5 minutes and record the

temperature of the centre tube. I will see if this tube huddled

between a bunch is the highest temperature after 5 minutes than the

rest. If the test tube in the bunch of 25 has the highest, my

prediction will be correct.

Fair Test:

To make my experiment a fair test I will do the following:

* Make sure each test tube is exactly the same size, I will do this by

measuring them.

* [IMAGE][IMAGE][IMAGE]I will make sure each test tube is the same

distance from each other, I will do this by making each set touch each

other in a circular shape like this: Centre ones measured.

* Same temperature to start with, measuring 65 degrees C each time.

* Left for the same amount of time, 5 minutes each.

Prediction

I predict that the bundle of 25 test tubes will turn out to be the

warmest after being left for 5 minutes. I think it will be followed by

the 17 bundle, then the 9, then the 5 and finally the one on it's own

will be the coolest. I believe this because:

1.) Cold air cannot cool them down on both sides as other penguins (or

test tubes) are here and so they stay at the same as the thing next to

them.

2.) The penguins do not lose heat from conduction and convection as

much because instead of
