3.Secure the slide on the stage so that it covers the hole and is in place with the stage clips hugging the slide into the L-shaped metal piece. 4.Looking through the oculars, slowly raise the stage using the course adjustment knob until you begin to see the specimen. i.You may need to adjust the width between oculars or the amount of light coming through the diaphragm.ii.You may also need to slowly move the slide around to find the specimen if you don’t see anything after moving the course adjustment knob.5.Once you see the specimen, slowly adjust the fine adjustment knob to focus.6.Record your results and move to the next objective lens. 7.Continue using the fine adjustment knob to focus the specimen, record your results, move to the next objective.8.If using the oil immersion lens you must apply a teeny tiny drop ofoil to the slide cover.Created by Diane Gibson

As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
