 * COLOR AFFECT HEART RATE **


 * ABSTRACT **

The purpose of this experiment was to determine if color affected heart rate. The hypothesis for the experiment was the color black would increase heart rate the most. The reason is in many cultures and through research it was found that black resembles death it is scary to most people which increases the heart rate. This experiment was done was by putting a person in front of a white tri-fold board, with a colored board behind it, to get a base heart rate. After the base heart rate was recorded the front white board was removed and the color board was shown. After the white board was removed, 30 seconds was allowed for the persons eyes to adjust to the color and then their heart rate was recorded. This process was repeated 3 times with the following colors, red, yellow, and black. The experiment found that black had the greatest increase in heart rate change of 14 beats/minute and next color was red with an increase of 4 beats/minute, and lastly was yellow had a decrease of 3.33 beats/minute.

A second experiment was performed to determine what filter of light would create the most voltage with a flashlight to a solar panel. For this experiment the clear filter had the most voltage of 0.602 volts, next was the yellow filter with 0.598 volts, then red with 0.591 volts, then orange with 0.575 volts, then blue with 0.537 volts, and last was green with 0.53 volts.

A third experiment was performed to determine if color of food affected choice. This was done by offering white and red color coated chocolate. Only one chocolate per person could be picked. In this experiment 60% of the people chose the red chocolate and 40% chose the white chocolate.


 * IMPROVEMENTS AND EXTENSIONS **

The first experiment could be improved by using electronically changing the color instead of the boards because in the experiment the boards fell over and distracted the person. Another way to improve this experiment would be creating a more calm and controlled environment so that the people are in a more controlled state.
