Bacteria in our school
So in class we were studying about bacteria. Me and my group had to swab 4 places. We chose to do the six grade bathroom sink nob and flusher, gym flood and lunch room table. Our job wad to to see witch place had the most bacteria. So we had a petrie dishes with 4 different sections. We got four different cotton q-tips and got them wet. We went around the school and seabed the ares. We can back to the class room and did a zig-zag pattern in the petrie dish. We taped the petrie dish shut so it wouldn't open in the incubator. After one day we check on them and saw that the six grade bathroom sink nob had the most bacteria. Second was lunch room table, gym floor and last was the six grade bathroom was the flusher. So there for the sick nob has the most bacteria in the school according to me and my group.
