 That thing that grows everywhere and in that place we learn and do homework in... A: for 48 hours of bateria growing we have seen that the girls bathroom door knob is the one with the most bacteria out of the four. E: our evidence for this answer is how many bacteria colonies that have grown in it's section and how big they are compared to the other bateria colonies in the other samples. I: In our project we didn't have any inaccuracies or scources of error. O: in our observations we saw that the drinking fountain we swabbed had no bacteria growing (THANK GOD). We observed that the door knob we saw bed was the one with the most bacteria, with 4 bateria colonies that were smooth yellow and whitish bumps. Mr. diPretes mouth was the second bacteria scorch that had 3 bacteria colonies that were yellow bumps. The smallest bacteria swab we did was the girls bathroom toilet handle that had only 2 bacteria colonies that were yellow smooth bumps. U: I understood that bacteria grows in multiple places, maybe not in bleached areas like the drinking fountain (we suspected that's why it had no bacteria) and that everywhere we go there's bacteria-even in hospitals!
