Actual Experimenting

On September 6th we had our first day of experimenting on our own we were taught how to swab every day items to check for bacteria. This was to show us how bacteria is present on anything and everything we touch on a daily basis. Now we just had to come up with good examples where people wouldn't expect bacteria. We decided to swab a crunched up, dirty dollar bill in hopes that we'd find a gold mine of bacteria. After swabbing, we took the sample and smeared it across a petri dish with a nutrient agar medium. It then needed to go in the incubator to grow.
