Part A In this activity, you'll grow bacteria in four prepared petri dishes. The first petri dish will have a sample
swabbed from your unwashed hands. The second petri dish will have a sample swabbed from your hands
after washing them with regular soap. The third petri dish will contain another sample from your
unwashed hands. The fourth petri dish will contain a sample taken after cleaning your hands with hand
sanitizer. What do you think the results will be? Write down your predictions for which samples will show
the greatest and least bacteria growth.
