The Purpose of this study was to see how glo germs do different things when heated up or cooled down and if the age of any of these affected how it produced light. Glo germ is used to teach kids how to best wash hands because when the glo germ is put under a black light one sees where the glo germ is, allowing one to see where hands are not washed very well. 1 mL of glo germ was put on the counter or in a beaker and tested to see when different things were done to it like put in the microwave or in the freezer on how much light was produced. During these experiments it was found that when the glo germ was put in the freezer it produced less light than when it was put in the microwave. When something is heated up it produces more energy than when it is cold because hot things have more energy than cold things.

This experiment can be improved by using more of an exact amount of bleach like 7 mL when cleaning the surface that has the glo germ on it. This way the out come of how much light is produced becomes more accurate and it isn't a guess like two sprays because the bottle could spray 3 mL and then the next spray 5 mL of bleach. This way the bleach would be more controlled and more exact. Future experiments that can be done are put glo germ in a cup and freeze the glo germ and then microwave the glo germ to see if it changes the amount of light that is produced and put glo germ in water and heat it up and see if it changes the amount of light produced. =====
