Low-Power Objective Lens
1. Put specimen on slide.
2. Put one drop of water on specimen
3. Put cover slip on slide at edge of water drop at 45 degree angle.
4. Lower cover slip onto the specimen to push air out.
Explain the steps of making a wet mount slide
What is the total magnification using low-power objective lens?
What is another word for the clarity of a magnified image?
To avoid fingerprints on the slide, which would affect the resolution!
Why should you hold a slide by its edges?
One hand on the ARM and one hand on the BASE!
What is the correct way to carry a microscope?
Fine Adjustment Knob

Controls amount of light passing through the opening of the stage
High-Power Objective Lens
Coarse Adjustment Knob
Moves stage for focusing with low-power objective lens
Supports slide being used
Supports the body tube
Supports the microscope
Low-Low Power Objective Lens
Reflects light upward through the diaphragm
Holds the low-power and high-power objective lens; allows the lenses to rotate for viewing
Holds slide in place
Contains a lens that magnifies 10X
1. larger field of view 2. You don't want to break the slide or the objective lens.
Why should you use the low power to locate specimens first, instead of high power?
Separates the eyepiece lens from the objective lens
