cava bio 204 s1.d05 Using a Microscope

QuestionAnswer
How do you carry a microscope? Two hands! One on the arm, one on the base.
Why do you keep a dust-cover on a microscope? To keep dust away from the lenses!
Why is the microscope we use in this class called a 'compound' microscope. It's one lens added to another. That's what 'to compound' means... to add to.
How do you clean the lenses of a microscope? With lens paper (or a soft lint-free cloth)
The eyepiece of a microscope houses the [...] lens ocular
Don't use the coarse adjustment knob with the larger lenses because you might... break either the slide or the lens
The lens close to the object that you're looking at is called the [...] lens objective
The shortest lens is sometimes called the... scanning lens
The part of a microscope that holds the slide is called the... stage
In which order do you select lenses when focusing a microscope? shortest to longest
With which objective lens do you use the coarse focus knob? Only with the shortest lens!
You're using the shortest lens of a compound microscope. After getting the image pretty much in focus with the course knob, how do you make it clearer? Move on to the fine adjustment knob.
