When you are ready to When you are ready to start:start:
3.Make sure microscope is on LOWLOW power!
4.Put stage all the way UP (you focus by slowly moving stage down)
5.Check the light setting (should be open)
![Page 20: Learning how to use the microscope. (COPY NOTES) 1.There are 2 kinds of microscopes: one lensmagnifying A. Simple: one lens (magnifying glass) B. Compound.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2be12/html5/thumbnails/20.jpg)

6.Carrying the Microscope:
Always use 2 hands!Always use 2 hands!

Other Things to Other Things to Consider:Consider:
7.Never use the COARSE FOCUS KNOB while on HIGHHIGH power.
![Page 22: Learning how to use the microscope. (COPY NOTES) 1.There are 2 kinds of microscopes: one lensmagnifying A. Simple: one lens (magnifying glass) B. Compound.](https://reader036.fdocuments.in/reader036/viewer/2022070401/56649f165503460f94c2be12/html5/thumbnails/22.jpg)
8. When putting the 8. When putting the microscope away (at the microscope away (at the
end of class):end of class):A. It should be on LOWLOW power.B. The stage should be all the
way DOWNDOWN (do this with the coarse focus knob!)
C. The light switch should be OFFOFF

into focus?into focus?
A. Check that you have one of the lenses clicked into place
B. Check that your disc diaphragm is allowing light to pass through (not closed)

TROUBLESHOOTINGTROUBLESHOOTING(CONTINUED)(CONTINUED)
• C. Clean off your lenses using LENS PAPERLENS PAPER. (Also, dirty slides are hard to focus on; so clean them, too!)
• D. GO BACK TO LOW POWER AND START OVER!

• Use a MAGNETICMAGNETIC field to bend beams of light; used to see things at much higher level of detail
• Can magnify images up to 1,000,0001,000,000 times!
