The main objective of the experiment was to determine the effect of temperature the mass specific metabolic rate (MR_MS) through oxygen consumption, if their body weight had an effect on mass specific metabolic rate and if the size/mass of the female swiss mice affected their response to the temperature. The different mice were placed within a plastic chamber and then placed in different variations of temperature of water (10°C, 15°C, 20°C, 25°C, 30°C). The procedure involved acclimating the mice up to the different temperature of ten minutes in each water bath then taking a recording of their oxygen consumption for five minutes and recording their metabolic rates. Our theoretical slopes of -0.25 and -0.33 where not significant or similar to

The respiratory metabolic rate (R) typically scales with body mass (M) according to the power function R=aMb, where a is constant (antilog of intercept of log-log) and b is the scaling exponent (slope in log-log plot). (Glazier 2014). Before Keiber published his theory on size, Rubner observed the scaling exponent b was 2/3 in his work of dogs of different sizes. .According to his theory, to maintain a constant body temperature, endothermic animals must metabolically produce enough body heat to exactly balance the amount of heat lost through their body surface, and since the body surface scaled as M^(2/3) so should metabolic rate (Glazier 2014). Max Kleiber then published in 1947 stating that the basal metabolic rate (BMR) did not scaled in proportion to surface area. Basal Metabolic Rate (BMR) is the rate at which the body uses energy while at rest to keep vital functions going such as breathing and keeping warm and produces important information for a wide variety of species. Some studies show that metabolic rates being higher in winter seasons compared to summer. Bird exhibit higher metabolic rates than mammals similar in size because of their high surface-to-volume ratio, and smaller species are more subject to high levels of heat loss (Hulbert
