At the same time, we conducted another experiment where we explored the difference if we washed our hands and dipped a finger int he agar. This second petri dish became our "Clean Hands" dish. Both petri dishes were labeled, sealed, and left alone for one week.
The results can be seen below:
"That's disgusting!"
"Eeeeeeew!"
"Even when we wash our hands, there's still germs"
"What is that????"
"We should wash our hands better"
