To focus on a the high power objective you must first start on the scanning objective. Once there you focus on scanning so that the specimen is clearly visible. After this you want to move up to low power and focus in using the coarse adjustment knob. Once adjusted you can move up to high power. From here you only want to use the fine adjustment knob. To make a wet you want to place a specimen on the slide. Once placed you add a drop of  water. After this hold the cover slip at a 45 degree angle over the slide and drop it. If done correctly there should be no air bubbles. To correctly add dye, add a drop of dye to one side of the slip. Next take a paper towel and place it on the other side of the slip. With the magic of cohesion the towel should absorb water and move the dye under the slip. This lab really helped improve my microscope skills by both helping me be more patient when focusing and helping me prepare slides.
