Activity 2: Virtual Lab

Complete the virtual lab, What Kills Germs

Activity 3: Destroying Bacteria Lab

Using the directions from Week 4, make gelatin to grow bacteria. Once you have a good growth of bacteria on the gelation:

Put a drop of hand sanitizer or other chemical microbe inhibitor on the gelatin where the bacteria is growing.
Leave for a day and see if the bacteria are killed. If they are you will see a clear ring in the area where you dropped the sanitizer.
Try different types of sanitizers such as Clorox, hand sanitizer, Listerine, or other household cleaners.
