Why Penguins Huddle

I am planning an experiment to find out why penguins huddle

I believe penguins huddle to keep warm using combined body heat. The heat is given to other penguins through radiation. This heat which is given out is then given back once the cold penguin is heated up this keeps them warm. To see if I am correct I will conduct an experiment. This experiment will help me find out if penguins huddle. I will need to show conduction this is when the heat energy passes through the walls of the tank by making the particles vibrate and this causes them to make the particles next to them vibrate. As the energy passes from atom to atom. As a result the heat passes through the tank and into the air surrounding the tank. This is considered the most important type of heat transfer in solids. Convection this type of heat transfer accurse in liquids and gases as the energy is carried around in atoms and molecules. This is when cooler water particles sink to the bottom and the hotter water particles rise to the top. This is a cycles and is continuous as the water keeps heating the cycle is caused by convection current as the energy moves around. Radiation this is when heat radiates from on area onto another through the movement in particles. The warm molecules vibrate and vibrate the surrounding molecules passing on the energy. Heat radiation can happen even if the areas are not touching. So the hot water tank could radiate its heat out into the surrounding area.

Apparatus List:

  • 12 test tubes

  • 2 elastic bands

  • Heat proof mat

  • Kettle

  • Measuring cylinder

  • Stop watch

  • 2 Thermometers

Method: 

Test1: All three experiments must be conducted on heatproof mats; this will catch any spills and stop the test tubes burning the table. I will put seven test tubes close up in a circle, this will simulate the huddle. The glass tubes will represent the penguins bodies the hot water will represent the penguins body heat. ...
