Exploring the Parts of the Microscope

Mr. Pierce provides a tutorial on the parts of a microscope. Students are instructed to use a half sheet of paper to label the parts as they are described. The tutorial covers the eyepiece, body tube, revolving nosepiece, objective lenses, arm, stage, stage clips, focus knobs, base, diaphragm, and light. Each part's function and importance are explained, with emphasis on magnification levels and proper handling of the microscope.
