I spent about 45 minutes on pooling all cultures, do staggered dilutions, and measuring OD 600nm before class. Due to this rush, I to go over the material list before class (I forgot steril water, tally, trash can, marker pens, and the cultures.)
Some students are not sure to use which grids on hemocytometer.
Some students open the plate and let them stay on the bench.
The lab last from 2pm to 4:30pm.
I should leave the protocol online and ask student to answer some questions.
