weeee i found my bio notebook from freshman year! mwahaha!



Steps for using microscope:

1) Always carry with 2 hands, one under base, one on arm.

2) Put the smallest objective lense over the slide opening and use the coarse adjustment knob to move the stage [the part the slide is on] as far away from the lens as possible.

3) Adjust the light source and diaphragm to allow the most light possible to pass through the slide. Open the diaphragm as far as possible.

4) Looking through the eyepiece, use the coarse adjustment knob to focus on the object.

5) The slide appears to move in the opposite direction because images are reversed and upside down in a microscope.

6) To focus on high power [meaning when you are using the biggest lense], move the body tybe and stage as far apart as possible, switch lenses, and adjust from the side. Only use fine adjustment. [This step is to make sure you don't break a slide.]

7) Always put the microscope away on low power.



I hope that made sense and helps [whereisfreds are just as good tho haha, i'm a dork]. I also have notes on what the pieces of the microscope are if you need to know that for your exam. Good luck. =0)
