 * THE STUDY OF HOW YOUR HEART RATE CHANGES WHEN DIFFERENT BODY PARTS ARE DIPPED IN ICE COLD WATER **

Joe N. 2011-2012


 * ABSTRACT **

The purpose of this study was to determine if heart rate will change when body parts are dipped in ice cold water. There are three different scales of temperature, Farenheight, Celsius, and kelvin. In the first experiment, a volunteer’s heart rate was measured and compared to the regular heart rate when a body part (head, left elbow, right elbow, left foot, and/or right foot) was dipped in ice cold water. The heart rate of the volunteers raised the most when left foots were dipped in ice cold water (see figure 1); the results are like this because ice cold water is a very foreign place for the foot to be in.


 * CONCLUSION **

 It is very foreign to a body part when it is dipped in water because body parts usually aren’t just dipped in to buckets of water every day, so when the parts were dipped in the water it caused shock to the heart which made it beat faster. This information could be important to a marine biologist in extreme weather conditions because it would be known that it is normal for heart rate to change when it is cold or warm so nobody should worry. It was thought that heart rate would change the most when the head was dipped in water but that was false because the foot is the most foreign body part in water therefore heart rate should change the most when feet are in water. Another experiment could be to do the same experiments but with different liquids.
