A microscope (from the Ancient Greek: μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small for the naked eye.
Parts:
Eyepiece Lens: the
lens at the top that you look through. They are usually 10X or 15X
power.
Tube: Connects
the eyepiece to the objective lenses
Arm: Supports
the tube and connects it to the base
Base: The
bottom of the microscope, used for support Illumination: A
steady light source (110 volts) used in place of a mirror. If your
microscope has a mirror, it is used to reflect light from an external
light source up through the bottom of the stage.
Stage: The
flat platform where you place your slides. Stage clips hold the
slides in place. If your microscope has a mechanical stage, you
will be able to move the slide around by turning two knobs. One
moves it left and right, the other moves it up and down.
Revolving Nosepiece or Turret:
This is the part that holds two or more objective lenses and can be
rotated to easily change power.
