"Even dry areas in my classroom have bacteria? When I started reading a book from the library about bacteria, the very first line I have read that “Bacteria grows mostly in moist area!” The next day, when I was in my classroom, I kept thinking about dry areas in my classroom that I touch all the time. If bacteria is everywhere, then those area should have bacteria, but which area is the dirtiest? Dry areas like the door knob, the faucet handle of the sink, and my desk are cleaned by the custodian everyday. I want to check how dirty are those areas after lunch. Which area has more bacteria? "
