Guide To Using A Microscope
- Ocular Lens (Eyepiece) - The lens that the microscope operator looks through
- Revolving nose piece - The part that holds the objective lenses and can be rotated to easily change power
- Objective Lens - Lenses used to see detail of specimen either high or low powered
- Arm - Used for carrying the microscope
- Stage - A platform where the slide is positioned with clips to hold it in place
- Stage Clips - Clips used to hold the specimen in place
- Coarse And Fine Adjustment - Knobs used to move the stage up and down for focusing
- Light Source - Light used to help see the specimen clearer
How To Bring A Specimen Into Focus
To bring a specimen into focus you must first choose an objective lens.
Most microscopes will have 3 objective lenses, x4, x10 and x20. Once you have chosen one of the objective lenses, you need to use the adjustment knobs to move the stage up and down until the specimen comes into focus. |
How To Produce A Wet Mount
To make a wet mount, first you place the specimen on the slide.
Then, using an eyedropper, put a drop of water on the specimen.
Place one end of the cover slip on the slide and slowly lower the
other end using a toothpick. This will help to prevent air bubbles
from getting trapped under the cover slip.

How To Draw Cells
Drawing cells is really easy. All you have to do is draw what you
see under the microscope. First you draw a circle on your paper,
then you draw about 3 or 4 cells that you can see under the microscope.
If you can see the nucleus in any of the cells, make sure to draw them too.
