This week in class we did a cool experiment. We took petri dished that Mr Finley made for us ( thanks!) and took samples of what our group would have bacteria and what wouldn't have bacteria. My group will check the progresss of it every day in class to see if our hypothesis we made were correct. The first time we will check the petri dishes will be on Monday, three dyas after we took the samples.
The experiment was in class to go into a bathroom(I went in the girls bathroom) and take swabs of what we thought would have bacteria. My group took a swab of the door lock because everyone touches it and the janitors may not have time to clean it. we also took a swab of what we thught was clean, the sink drain. We thought this would be clean since all of the water and soap go down it and that wold wash out most of the germs(hopefully!). I can't wait until monday to see the progress of the petri dishes.
