Bacteria in Our School
My original question about bacteria in our school was if there's more bacteria on things that get cleaned often but touched often, or things that don't get touched often and very seldom cleaned. I swabbed the basketball, the water fountain nozzle, the microphone in the auditorium, and the door handle. It turns out the microphone has the most bacteria by far. There was one big colony of bacteria growing. The basketball had the next most, then the handle and the nozzle had little if any bacteria. I originally predicted the handle would have the most bacteria but now I know the things that don't get washed often are the dirtiest.

I'm surprised that the microphone in the auditorium had the most bacteria. That's really gross!
