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.
