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. They are multiplied together, so the total magnification is 400X on the maximum setting.
Turn the switch on the base to select the base light (instead of the upper light). Turn the objective to the lowest magnification. Move the slide around until you see the specimen, and use the coarse adjustment knob to focus. Also use the fine adjustment knobs, if your microscope has them. The protist organism you see is the entire organism.
Write down what you see (shape, size, and any structures) at the lowest magnification. Repeat with the other two objective magnifications, and record what you see under each magnification. Identify any cell structures you see.

Answer:
Paramecium is a genus of eukaryotic unicellular ciliates and is widely studied as a representative of the ciliate group. Paramecium is widely distributed in freshwater, brackish and marine environments and is common in stagnant aquariums and ponds. Some species are widely used in classrooms and laboratories to study biological processes because they are easy to culture and easily induce binding and division. Its usefulness as a model organism has led some ciliate researchers to characterize it as a "white rat" in the phylum Ciliate.
Explanation:
Paramecium size range from 50 to 330 microns (0.0020 to 0.0130 inches). The cells are usually oval, rectangular, foot or cigar-shaped.
The body of a cell is surrounded by a rigid but elastic structure called a membrane. It consists of an outer cell membrane (protoplasmic membrane), a layer of flat membrane-bound sac called the alveoli, and an intima called epiplasma. The cuticle is not smooth, but consists of hexagonal or rectangular indentations. Each of these polygons is perforated by a central opening with a single cilia protruding. Between the alveolar sac of the cuticle, most Paramecium species have a dense spindle-shaped trichocyst, an explosive organelle that secretes thin, non-toxic filaments often used for defensive purposes.
