It's like a scientific approach to the mirror picture

Today in lab we used UV light to see if it will inhibit bacterial growth. Some hospitals use UV lights in the patient rooms as an antimicrobial approach. Dr. Pathakamuri showed us a container where they used UV light in this way.
Lisa made the comment of scientific mirror picture -->

Then it was our turn. We divided a plate in half and shared it with Teresa and Lisa. Each group streaked their unknown on their side. Then we divided the plate in half the other way and placed a notecard over half of each of our unknown. Then the plate was incubated for Thursday.


Then we got to see the Steripen. This uses UV light to sterilize water and make it safe to drink. Dr. Pathakamuri mixed all of our unknowns into water then made a control plate and then he used the Steripen in the water and created an UV light treated plate. Then the plates were incubated for Thursday.


The last experiment we did was making yogurt. First we boiled milk then cooled it down to 37 degrees Celsius. This was sped up by pouring it from cup to cup. Then we added Kefir to one cup and already made yogurt to another. Then it was incubated and Dr. Pathakamuri will check them tomorrow.
