Investigation of Surface Area: Volume Ratio and its effect on Body Temperature Introduction There are many factors that determine how quickly or slowly heat is lost. Some of the factors are as follows: amount of water, shape, temperature and surface area to volume ratio. The aim of this investigation is to examine how variations in surface and volume ratios in organisms lead to variations in heat loss. In theory a larger object should lose heat more slowly than a smaller object will as the larger object has a lower surface area to volume ratio than the small one so the heat will have further to travel. An example is the robin. In the winter the robin fluffs up into a spherical shape to give itself a smaller ratio so it retains heat more efficiently. In the summer it makes its body sleek and thin, giving itself a larger ratio so it...
