Human+Inaccuracy+When+Measuring+Temperature

Siobhan C   Cary Academy ** ABSTRACT  ** The purpose of this experiment was to look at human inaccuracy, because the brain measures the temperature of the skin by comparison, the previous temperature of the skin can affect the temperature that the subject thinks the water is. It was hypothesized in this experiment that more people would be inaccurate at measuring the temperature of the water that their feet were put in. The method of this experiment was: the subject of the experiment was blindfolded and told to relax their feet; their feet were then put into buckets of water about 5 degrees different in temperature. Their feet were left in those buckets for about 30 seconds and then moved to another bucket. They were then asked to tell which foot was colder and warmer. The results were recorded. The results of this experiment was 6 to 4, the 6 representing the number of inaccurate people and the 4 representing the number of people who were accurate. These results were generally as expected but they were also a lot closer than expected; there was only a 20% difference.
