1. EYEPIECE - the part of the microscope that you look through
- contains a lens that has a magnification power of
10x  
2. ARM - supports the upper portion of microscope
- is used to carry the microscope
3. STAGE CLIPS - hold a slide in place on the stage
4. COARSE ADJUSTMENT - the large knob that will

2. 6. BASE- supports the entire microscope
- also is used to carry the microscope
7. LIGHT SOURCE- sometimes a mirror and sometimes a built
in light
- directs the light through the opening in the stage,
through the sample, and up through the body tube
so you can see the object
8. DIAPHRAGM - increases or decreases the amount of light
entering through the stage so you can see
the object more clearly   
 9. STAGE- supports the slide which holds the object being
viewed 
10. HIGH POWER OBJECTIVE - lens that has the highest
magnification; the microscope you will be
using has a high power of 40x 10 9 8 7 6

3. 11. LOW POWER OBJECTIVES - lenses that have the
lowest magnification; the microscopes you
will be using have a low power of 4x and 10x
12. REVOLVING NOSEPIECE - holds the low and high
power objectives and can be rotated to change
magnification
13. BODY TUBE - maintains the proper distance between
the eyepiece and the objective lens; allows
light to pass upward to your eye 13 12 11
