Your Microscope: Parts and Focus
This lab is a beginner microscope lab. Students will learn the names for the
parts of the microscope as well as how to focus the microscope. If your students
are experienced microscope users, you might find they do not need to do this
lab. Through the remainder of this course, it will be assumed your student has
performed this lab, and knows the terminology and how to use a microscope.
The instrucons for the first few microscope labs are very long. They are wrien
for those students who have never used a microscope and want to know it all. They
are instrucon manuals detailing proper technique, procedure, and terminology.
Later in the text, the instrucons for the microscope labs shorten considerably.
Through connued use, students will become very good at using a microscope.
Part 1: Parts of the Microscope
The purpose of the first part of this lab is to teach students the names of all the
relevant parts of the microscope. See the next page for correct labeling.
Students are not expected to memorize microscope terms. I expect they will
learn the names of the parts of the microscope through connued use.
Part 2: How to Focus Your Microscope
This secon instructs students on the correct procedure for
focusing a microscope. Students are expected to draw three
pictures, each is a microscopic view of the paper and ink at one
of the three magnificaons. The oil immersion lens will NOT be
used with this lab. Next, students will look at a color picture from
a catalogue. It is really interesng to see how all the colors in a
catalogue are made by combining the same four colors of dots in
different proporons.
When viewed without
MS letters look solid.
Under MS there are
parts of letters that
look sprayed.
This is an example of a completed
microscope view sheet. Throughout this
guide you will fi nd several such examples.
These are for reference only. What your
student views through the microscope could
be vastly different than what is pictured in
these examples.

Bonus queson: Do you know the name of the molecule that
makes up the fibers you are seeing at 400x magnificaon?
cellulose
“K” indicates black in the four-color print processing used for
your catalogue picture (CMYK). But it doesn’t stand for the word
“black.” Research what it does stand for and why. K stands for
the word “key.” Way back when color prinng started, the black
plate was called the key plate because it contained the arsc
detail or “key” informaon. Today we say that K means “black,”
so as not to confuse it with B (blue) in the RGB color model.
