Yesterday in class we did an experiment which was to find a place where you think will contain bacteria, we took a cotton swab and rubbed it on a place where we thought there was bacteria. Then we rubbed the swab in the petri dish. 3/4 places we chose to test for bacteria were in the bathroom. We did this because we know tthe sections is because the places where we took the sample of aren't really clean places. hat bacteria is in places that aren't really clean and in dark places. I predict that bacteria will grow on all four sections of the pertri dish because we chose a bottom corner of a locker, the drain of a sink, a toilet handle, and a outer part of a urinal. The reason I think bacteria will grow in all of them is because I know that they aren't really clean places.
Today, web links were disabled I wwould've posted it but I couldn't anyway I found this article on lifewhile.com and it said the top 5 dirtiest places in school, bathroom was #3 on the list
