Looking at the constructed graphs, the respiration rate of the lizard is keeping at the same rate steadily, and there isn’t a huge increase or a huge decrease. This means the lizard was still for most of the time. But this is totally different for mouse, mouse respiration rate at room temperature trend is going up really fast, so it means the mice was in a panic at room temperature. The respiration rate at both and cold temperature for mouse are all increasing unlike the lizard.

The hypothesis is as temperature increases, the respiration rate for endothermic animals increases. As the temperature decreases, the respiration rate for ectothermic animals increases. The data rejects the hypothesis, the hypothesis indicates that endothermic animals’ respiration rate will be increase at high temperature, and that ectothermic animals’ respiration rate will increase at a cold temperature. However, the data indicates endothermic animal’s respiration rate was at 587.6 ppm at cold temperature, which is rejecting the hypothesis saying that it will increase in hot temperature. The data also indicates ectothermic animal’s respiration rate was at 38.1 ppm at room temperature, which is rejecting the hypothesis saying it will increase in cold temperature.

 Warm blooded animal body temperature stays the same even though the temperature changes, while cold blooded animal body temperature changes when the temperature changes. One of the possible errors that might changed the result of the experiment is during the lizard cold temperature testing, take out the lizard every two minutes to check if he is alive, and he nearly died for two times. So the temperature wasn’t consistent and the respiration rate isn’t accurate. An extension for the experiment might be how different kinds of food affect the respiration rate on both warm and cold blooded animals.
