Bacteria destroying test

Abby, shimmi, brittany and my self gathered bacteria from the PE staff room and put it in the container. We then used water, sanitizer, bleach and a control. These were used to test to see which things would destroy the bacteria. So far after a day, we have seen that the bleach has destroyed it the most.
I think that we could not do the same test with viruses because viruses effect living things even though they reproduce. Maybe if there was some living things inside the agaar plates
