If there are Paramecia in your field of view you probably will recognize them immediately. Often, however, students do have difficulty both finding a Paramecium, and after they have found one, making it move slowly enough so they can study it at high magnification. The trick to finding a Paramecium is to scan the entire slide quickly using the scanning lens. Then, if you do not find one, make a new slide and search again.

Paramecium -- Paramecia are quite large, straw-colored, slipper-shaped and move

probably will recognize them immediately. Often, however, students do have difficulty both
finding a Paramecium, and after they have found one, making it move slowly enough so
they can study it at high magnification. The trick to finding a Paramecium is to scan the
