In order to focus a high powered lens, you have to turn the knob using the scanning lens. Then rotate the high powered lens. To make a wet mount you must get a small sample to place on a slide, then add a few drops of water and place the slide cover on top. Press firmly until it sticks but don't crack the glass. To stain a slide, you put a drop of stain on the edge of the slide cover. Using a small paper towel,  put it against the opposite end of the slide cover and it will act as a magnet. When the stain has been pulled in it should cover the specimen on the slide. I had really no knowledge of microscope usage and it helped me understand new aspects of the microscope.
