**THE STUDY OF DIFFERENT SOAPS REMOVING GERMS ON HANDS** **Julian S** **2011-2012** The purpose of this experiment was to determine whether or not different soaps change the amount of germs that are removed. Soap removes bacteria from human hands by surrounding the up to 40 million bacteria cells in hydrophobic and hydrophilic anions that lift the dirt up and out of the hand. Soap was applied to test subject’s hands and washed for different amounts of time, washed in different temperatures of water and different types of soap were used. In the end it was found that more gritty soaps were best, warm water was best and more time was best. These results are true because when more and more Glow Germ is added, the more Glow Germ is going to glow
 * ABSTRACT **


 * CONCLUSION **

The best way to wash anything is with gritty soap, warm water, and for a long period of time. The data displayed here is important because it shows information on the five second rule and washing hands. The prediction that warm water, gritty soap and longer periods of time washing would remove more germs was correct. Some follow up experiments that could be done could be testing if different types of soap work best (foam, jelly, gritty)
