Today in class we are going around the school trying to find were the most and least amount of bacteria is found. In my group, we think that the place to find the most bacteria is in the cafeteria on the finger scan. The second place were we think that we will find the most bacteria is in the Middle School Hallways on the ground. The two places that we think won't have a lot of bacteria is the nurses office and the ceiling in the middle school hallways.
After we got our bacteria on the petri dish, we put the petri dishes in the inubator. An incubator keeps things at a nice temperature so that they can grow. We put the bacteria in there because the incubator will help the bacteria grow and it will make it go faster. We also learned wat range of tolerance is. Range of tolerance is the maximum and minimum limits something needs to maintain to survive. An example of range of tolerance is the timberline on mountains. The timber line is the point on a mountain were trees can no longer survive.
