The Study of Germs Reacting to Different Amounts of Water Jackson B Cary Academy 2011-12

Abstract The purpose of this experiment was to see how different amounts of water affected the germ count on the hand. The introduction answers different questions such as, what is soap and what is the electromagnetic spectrum. The original method was putting hands under water for different of time than measuring how much light the germs gave off. It was discovered that the longer you do wash the more germs come off your hands.

Conclusion This study shows that the longer hands are washed the better. These studies were important because imagine eating something that was only on the ground for 5 (sec) but germs had already started to reproduce. The hypothesis was correct because it was that germs would become attached to the hydrophobic tails of the soap and fall off. A follow up experiment could be dipping the hand in different liquids than measuring the Light (lux).
