The purpose of this study was to figure out if different types of hand sanitizers and hand soaps kill different amounts of bacteria. Soap has two parts which attract to water and fat and because bacteria has a fat case, the bacteria is carried off hands. The method of this experiment was dusting glow germ onto hands, the light of the glow germ was found using a light probe, hands were washed and the light was measured again to determine the amount of germs killed. The results were that soap kills more than hand sanitizer, and natural bacterial killers such as lemon juice, lime juice, etc. kill just as many germs as soap. These results were what they were scientifically because research and these studies have shown that soap, with many different bacteria killing elements (friction, soap, water, hand drying) all amount to making a better end product when cleaning hands. If I were to change something about my ISP paper it would be to do more creative experiments, because my data was all fairly similar and I wish that I would have tested things like how much soap you put on your hands and see if that effected the data. Over all I just wish that I had done more various types of experimenting and then I probably would not have gotten such similar data and my project might be more interesting to viewers and teach people more than what they see repeated. In future it would be interesting to find out if different amounts of soap kill different amounts of bacteria or if it was tested if drying hands with different textures of paper towels or cloth towels if germs are carried with them and if the amount of germs is affected at all. It would also be interesting to test washing hands for different times.
