How To Use a Compound Microscope to Study Cells
Microscopes are important tools used to view things we cannot see with the naked eye. Cells are the building blocks of living organisms, but we often need microscopes to study them. Microscopes come in many forms, but compound microscopes are a common choice for amateur scientists.

1
Uncover and place the microscope on a flat surface near a power source. Plug the cord into the outlet and turn on the microscope.
-
2
Make sure the the microscope is on the lowest magnification setting (the shortest objective lens) and place your cell sample slide on the viewing tray. Secure the slide under the pins if provided.

3
Look into the eyepiece and adjust the large knob until you achieve a general view of your sample.
-
4
Continue looking into the eyepiece and turn the smaller knob to refine your sample's image while adjusting the lighting as necessary. The image should eventually come into sharp, clear focus. Make a note of your observations.
-
5
To study the cells in more detail, you can increase the magnification of the microscope. Rotate to an objective lens with a higher magnification and then repeat the adjustments with the two knobs and lighting as in steps 3 and 4.
-
6
When you are finished making your observations, remove the slide and return the microscope to the lowest magnification setting before shutting it off.

Tips & Warnings
Be sure to use both hands when carrying the microscope to prevent damage. Only use lens paper to clean the lens. Other materials may scratch or damage the lens.
Always start with the lowest power lens. This will prevent any accidental breakage of slides or the lens itself.
