The sink nob has the most bacteria on it. My evidence is it has the biggest mark in the triangle. Maybe we did not swab the flusher enough and that is why there is no bacteria. I would think that would be one of the dirtiest places in the school and it did not grow anything. We must have done something wrong there. There is white dots in some of the places. I don't want to touch too much stuff at school. I want to wash my hands so much! I really enjoyed this experiment because it taught me to be more carefull in the gross dirty areas.
