Today we looked at our results! Based on what we saw we were quite surprised. We compared samples that had been exposed to different surfaces to control samples that had been left “clean.” We tested 6 different sites. From our observations of germ colonies the worst place for germs was the bathroom floors that we tested. No shock there, but Surprisingly! The toilets we tested looked much cleaner than the chromebook keyboards we sampled. Think about that! Our chrome books were grosser than a toilet seat?

Here are pictures of our results.
