Yogurt Experiment!!!

We obtained yogurt and milk and proceeded to put a small amount of yogurt and milk in two separate cups. For one cup we heated the milk and the yogurt and then put it into the yogurt incubator for about a day. For the other cup we just put the cup into the yogurt incubator without heating the milk and the yogurt.

After a day of incubation, one of our fellow microbiology classmates took the two cups and put it in the refrigerator.

Then when we returned to the lab the following day we tasted and looked at the two yogurt cups. We found that heating the milk and yogurt not only tasted better but the consistency was a lot better than the not heated cup. The cup that we did not heat looked more liquidly than the other one and tasted really sour.

Here are some pictures of Rose tasting the yogurt and what the yogurt looked like!
