Investigation to demonstrate how the surface area and volume affects the heat loss in animals Planning Aim: To investigate how surface area and volume of an animal affects the amount of heat lost. Planning a simple procedure One standard test tube, one boiling test tube, and one centrifuge test tube will be filled with water at 40°C. A thermometer will be placed in each tube to measure the decrease in temperature of the water. This will be timed for 300 seconds using a stopwatch. The temperature of the water will be recorded every 30 seconds. Preliminary Work A prior experiment similar to the one outlined above, was carried out to determine the sizes of the test tubes. The surface area and volume for each tube used were * Standard Test tube Surface area = 2.69 cm2 Volume = 18 cm3 * Boiling Test tube Surface area = 5.73 cm2 Volume = 44.66 cm3 * Centrifuge Test tube Surface area...
