My project is about the reaction time of a human being. I tested 3 subjects using two computer tests. Before the tests, each subject measured their temperature with a digital thermometer. They recorded the temperature and began the test. I made this project because I always wanted to know why at some points of the day I was very slow in doing things and at some points I did really well and did some things quickly. I wanted to know when and why I would be slower. I believed that the younger the person, the better their reaction time and body temperature would be. I also believed that the morning would be the best time because you were rested and ready for the day. My goal in the project was to discover the variables on reaction times. For example, body temperature or time of day. Even if the age of the subjects is different. Another goal is to find out if the variables will affect my project in more than one way. Goals are not always as planned as I would like, however a goal that is always planned would not make the project fun. The results I would expect if younger subjects would have had better results because the energy level is higher. Another expected result was that the person with the lower temperature will be more likely to have a better reaction time. I believe this because the fresher you are the less stressed you are, so your reaction time will be faster as you focus on the task. So after this I had to do some research on all the things I learned. I studied the process of this project and how to execute it. I learned that there is an entire system of the human body that explains when it is strongest called the circadian cycle. This cycle is the 24-hour human day cycle. The cycle includes...... half of the paper......on time after the shower. Furthermore, subject 1 had an elevated temperature of 36.75 degrees Celsius after lunch. Subject 1 after lunch had a reaction time of 0.28 seconds. Subject 2 had a reaction time of 0.41 seconds before taking a shower. At the same time it had a temperature of 36.41 degrees Celsius. He/she had an average reaction time before going to bed, the lowest temperature of the day was 36.36 degrees Celsius. Even then he/she had his/her second lowest reaction time of 0.29 seconds. The point for this argument is that it was within the limits of high temperatures corresponding to slow reaction times. Finally, subject 3 had a different way. He/she had the highest temperature after the shower but also the best reaction time. Furthermore, he had the lowest temperature after a night's sleep in bed as well as the lowest reaction time. This is the reaction time!
