Today in class, we tried to find out who started the disease. We could not find this out because to many people got sick. Also, the class before us did not clean out the test tube well enough because some of us started out with pink(represents illness), but we were not suppose too only if Mr. Finely put the indicator in our fluids. We wrote down everyone we transferred fluids with in order. Then we made a tree diagram with the list of people we transferred with. This would help us find out who patient zero was. Since, too many people got sick we could not track the person down that got everyone sick.
In the tree diagram if the person in our diagram ended up sick we would put an X next to there name. This would help us find out who patient zero was. Today in class, we redid the experiment so we could get better results, but we winded up not having enough time to make a tree diagram. In the experiment we got an amount of people to transfer fluids with. Mr.Finley told us the amount. Then, we went around with the transfer pipets and transferred fluids with other people. If our fluids turned purple we were sick. We wrote everyone we transferred with so we could make a tree diagram. Then, Mr. Finley came around and put indicator in our fluids if it turned purple you were sick. Then, we had to clean out the test tube and throw away the transfer pipets. in the other classes they did not clean the test tubes well enough so some of the indicator were still in the test tubes.
