Germs and Bacteria

This very short week, the students learned about being healthy. We had two Dartmouth Grad students come in and do a hand washing lab. The students tested the bacteria on their fingers: first with a finger as a test level, then with just washing with water, then washing with soap and water for various times throughout the class and finally a few students tested using antibacterial soap. For fun the students were also given swabs to test for bacteria in random locations around the room.

We let the bacteria grown for 48 hours before getting a chance to look at the petri dishes. The Dartmouth students brought in a high tech powerful microscope where the students could look closely at the colony of bacteria that were living on their hands. Most all of the students were totally grossed out by what they saw living on their hands and around the room. Check out some of the pictures below.
