A student missed the laboratory period where the use of the microscope was demonstrated. The instructor asked the student to read the description in the laboratory manual and then proceed to examine bacterial cells with the oil immersion lens. The student skimmed the directions and began. After about 15 minutes of struggling, the student gave up in despair without seeing anything. Below is a detailed description of what the student did. How many mistakes did the student make and why didn’t the student see anything?a. Plugged in the microscope and turned the light source to maximum intensity.Made a wet mount and placed it on the stage with the low-power objective lens in position.Tried to focus with the coarse adjustment, but decided the bacteria were too small and needed to be seen with the high-power objective lens.Rotated the high-power objective lens into position, but saw the lens would likely touch the slide, so lowered the stage so that the objective lens rotated freely.Tried to focus with the coarse adjustment knob, but still saw nothing.Decided to switch to the oil immersion lens, but still saw nothing.

The microscope is an instrument is used to see objects that are too small where it makes enlarges…

Question

A student missed the laboratory period where the use of the microscope was demonstrated. The instructor asked the student to read the description in the laboratory manual and then proceed to examine bacterial cells with the oil immersion lens. The student skimmed the directions and began. After about 15 minutes of struggling, the student gave up in despair without seeing anything. Below is a detailed description of what the student did. How many mistakes did the student make and why didn’t the student see anything?

a. Plugged in the microscope and turned the light source to maximum intensity.
Made a wet mount and placed it on the stage with the low-power objective lens in position.
Tried to focus with the coarse adjustment, but decided the bacteria were too small and needed to be seen with the high-power objective lens.
Rotated the high-power objective lens into position, but saw the lens would likely touch the slide, so lowered the stage so that the objective lens rotated freely.
Tried to focus with the coarse adjustment knob, but still saw nothing.
Decided to switch to the oil immersion lens, but still saw nothing.
