The Dirtiest place in the School

Hypothesis:I think the bathroom taps are the dirtiest place because people clean there hands and the have to turn it on.

Locations:
Rubbish bins  Food room bench         door handles   inside toilet door
toilet seat       under tables                  table tops       outside toilet door
gym floor        library book                 glass windows  General air
under J block  chrome book keyboard  Bathroom tap  our hands Drinking fountains

Equipment: Agar dishes,cotton buds, cellotape

Method: Take cotton bud and wipe it firmly over the surface.
wipe cotton bud across the agar jelly carefully.
seal the agar plate with cellotape and write the location on the tape
store upside down in a dark location

                                                                 what we found?
                     The cleanest place in the school was Mr Stock door handle because it didn't have any bacteria on it.
the dirtiest place in the school was Miss Richardson laptop because she never cleans it and it had lots of bacteria.
I was surprised by Miss Richardson's laptop being the most dirtiest place in the school.
