Starting with the Microscope
1. Carry the microscope with two hands. One hand is on the arm and one hand is on the base. 2. Put the microscope down, at least 5 cm. away from the edge of the workspace. 3. Clean the optical and objective lens peices. 4. Before starting, make sure you have the low power objective lens (the red one). 5. Now you're ready to start!

Microscope Definitions
Ocular Lens- The ocular lens is also called the eye piece, which you look through to see your slide. Low Power Objective Lens- The low power objective lens magnifies the image 10X. High Power Objective Lens- The high power objective lens magnifies the image either 30X or 40X. Revolving Nose Piece- The revolving nose piece hold the objective lens and can be tuned to change from on magnification to another. Body Tube- The body tube maintains the correct distance between the ocular lens and objectives. Coarse-Adjustment Knob- The coarse-adjustment knob moves the body tube up and down to allow focusing of the slide image. Fine-Adjustment Knob- The fine-adjustment knob move the body tube very slightly to bring the image into sharper focus. Stage- The stage supports the slide, the little tray, or table under the slide. Stage Clips- The stage clips hold the side in place. Diaphragm- The diaphragm controls the amount of light coming through the stage. Light- The light provides a light source for viewing a slide. Arm- The arm supports the body tube. You hold the arm with one hand and another on the base when you are carrying the microscope. Base- The base supports the whole microscope. You hold the base with one had and the arm with another while carrying the microscope.

Ending with the Microscope:
1. Make sure you turn off the microscope first. 2. Wipe the lens with parchment paper. 3. Put the low power objective lens back to the begining. 4. Lower the stage down by turning the coasre adjustment knob. 5. Put it back on the cart, using two hands, one on the base, and one on the arm. 6. Make sure, if there is a wire, to wind the wire around the arm.
