Scenario 1:
A student is tasked to observe a leaf under a microscope. She cut a small piece, put it on the slide and covered it with a cover slip. She then tried to use the scanning objective, focused the specimen using the coarse knob and switched to low power objective. She focused the specimen using a high power objective, but she cannot see the specimen very well. What do you think is wrong with the procedure?
