Aim: The aim of this experiment is to investigate how groups of animals conserve heat in cold climates. Hypothesis: I hypothesise that a huddled group will lose less heat than an isolated animal. This is because the exposed surface area of a group of animals is less for each animal than an isolated animal (as shown below). S. area of 1: 10 + 10 + 10 + 10 = 40 cm S. area of 4: 40 x 4 = 160 cm However...

Plan: We will use the same amount of water (35ml) and take the temperature at regular intervals. All water will start at the same temperature. We will continue the experiment for 5 minutes. Apparatus: This is how the boiling tubes (used to represent the animals) will...
