Put the paramecium or protist slide on the base of your compound microscope. Secure the slide on the base with the clips, and set the objectives on the lowest magnification. If you’re using an Edmentum microscope, your eye piece has a magnification of 10X. The objectives have 4X, 10X, and 40X magnification.
