    Read the Microscopy chapter in your textbook prior to lab.

    1. Compare and contrast Bright-field, Dark-field, and Phase Contrast microscopy.
    2. What would the total magnification be for the following?

    Objective magnification

    Ocular magnification

    Total magnification

    1. Why is it often necessary to stain specimens?
    2. Give an advantage of dark-field or phase contrast microscopy over bright-field.

    Parts of the Compound Microscope

    Label the parts of the microscope indicated by the arrows:

    A laboratory microscope on a dark surface, labeled with parts such as the eyepiece, stage, and focus knobs.

    Laboratory microscope positioned on a black surface, featuring a large eyepiece and adjustable knobs.

    Microscope with labeled components, including eyepiece, stage, and focus knobs, set against a neutral background.
