In-person Serial Dilution (spectrophotometric readings): You are not expected to submit anything here. This will just serve as a placeholder and will be graded based on your in-person performance in this section of the exam. You are to dilute crystal violet in series 3 times, just like we did in class (diluting with water). You are making 1:10 dilutions each time. When you are finished with your dilutions, raise your hand and a member of the teaching team will come over and take your 8-well strip from you. PLEASE ensure that it is labeled with your USUAL seat number (on the tab next to the well where you started – with the little extra tab pointing downwards). If you messed up and need a new 8-well strip, please raise your hand and we will provide you with one. You will not be penalized for this! However, when you do give your 8-well strip over to a TA, you will be considered done with this part of the exam, and you won’t be able to redo it. You can turn in your strip at any point during the exam, so there is no rush to do it all in one go or to do it first. HINT: In your 8-well strip, the last 2 wells will be negative controls. Wells 1 & 2 will be the same, Wells 3 & 4 will be the same, and Wells 5 & 6 will be the same.
