DOES TEMPERATURE AFFECT REATION TIME Joe M. 2011-2012

ABSTRACT The purpose of this study was to determine if temperature affects reaction time. In the introduction it talked about key thing that let people have reaction time. In the main experiment the subjects hand was placed in ice water for 0, 15, 30, and 45 sec to see if that affected the reaction time. In the main experiment it showed that when subjects put the hand in ice water it affected the reaction time, the reaction time was the fastest at 15 sec. The reaction time was the fastest when the hand was put into the ice water for 15 sec because it woke up the subject.

CONCLUSION In this experiment it was found that when subjects put the hand in ice water for 15 sec it makes hand eye coordination faster. When the hand was in the ice water for 30, and 45 sec it was almost the same as if it was in the ice water for 15 sec. This data is important to the world because people never know when they need a fast reaction time. The hypothesis was incorrect; the hypothesis said that when subject’s hand was in ice water the reaction time would be slower but it was actually faster. A follow up experiment could be if warm water affects reaction time. Another follow up experiment could be if putting subjects hand in ice water and warm water affects subject’s strength.
