Understanding GermsHealth and Wellness
- Mr. Greg Gaines
"My project experiments if the 5 second rule is verifiable, using the analysis of bacteria colony growth, and colony morphology on petri dishes, with food, and surface. I chose this project because this problem is too long gone, and it’s an interesting controversy that needs to be solved. Also, because as a kid I used to eat food off the floor myself, I was curious about the 5 second rule. I found that the 5 second rule is mostly true for dry food that falls on carpet surfaces. For wet food on any surface, bacteria growth was high, and this rule isn’t likely to be true. This project is important because it will help prevent diseases, and keep everybody, including kids safe from pathogens, and harmful germs/bacteria. "
