4. Magnifications Eyepiece is 10x Low power - 4x = ________x Medium power - 10x = _______x High power - 40x = _______x

5. Putting Microscope away Adjust course adjustment knob to its lowest position Remove slide Move objectives to “scan” or “low” power Power off and unplug Wrap cord and cover Move it back away from the edge of the lab table

6. Rules Never move course adjustment knob Always tell teacher if you Break a slide Microscope doesn’t work Or you cant get specimen focused Only carry microscope from its arm Always focus on low power
