Serial Dilution Activity

Today, in class, we learned about dilutions. We specifically learned about serial dilutions and how they work. After the lecture, we did an activity in the lab. It wasn't an actual lab so we didn't have to do a pre lab quiz. This, I gotta say, was one of my favorite things about this activity. The activity asked us to make a serial dilution. First, we poured 10 ml of water in a cup and put 20 drops of food coloring into it. Then we got another 9 ml of water and took 1 ml of the first solution, and put it into the 9 ml solution. We repeated this procedure until we didn't see any water. This was it.
