Parts of a Microscope Directions: Read each paragraph. Find and highlight the answers to the questions
below the paragraph. Write the answers to the questions.
Before the microscope was invented, people thought there was
nothing smaller than the smallest things that could be viewed with the
human eye. Then early microscope designers like Robert Hooke changed
all that. Robert Hooke made a microscope out of two lenses placed at
opposite ends of a long tube. The tube was attached to a stand, and an oil
lamp provided light. Hooke also added a mirror to focus the light onto the
object being examined. He used his microscope to magnify visible things
like fleas.
1. Who made the first compound microscope?
2. Describe Hooke’s microscope.
Today, most microscopes are called compound light microscopes,
and use two lenses for greater magnification. The upper lens is called the
ocular lens or eyepiece, and the lower lens (or lenses, as there may be a
choice of sizes) is called the objective lens. Label and Color the ocular lens light blue. Most eyepiece lenses are 10X magnification. The
magnification of each objective lens will be marked on the side of the
objective. To determine the total magnification, multiply the eyepiece
power (10X) times the magnification of the objective you are using.
3. Why are today’s microscopes called compound scopes?
4. What is the upper lens called? What is its magnification?
5. How is TOTAL magnification determined?
21
Always begin focusing a microscope on the lowest power and then move
to the next higher power and refocus. Label and color the low power
objective pink and the high power objective red. The eyepiece is at the
top of the body tube. Label the body tube. The objective lenses are
located on a revolving nosepiece at the bottom of the body tube. Label and color the nosepiece brown and the body tube orange.
6. How should you always begin focusing?
7. Where are the objective lenses located?
When an image is formed, it is actually magnified twice. First, the
image is formed at the bottom by the objective lens. Then the image is
projected through a tube and magnified again by the eyepiece at the top.
The image is always upside down, so what you see through a microscope
shows up as the opposite of what you are doing. Any movement of the
object also shows up in the opposite way. When you move an object to the
right, it appears to move to the left, and when you move it up, its image
moves down. Use black arrows to show the pathway that light takes
through the microscope to your eye.
8. How does the image appear to your eyes?
9. If you want the image to move to the left, how must you move the
slide? Explain why.
When setting up a microscope, be sure to carry the scope with two
hands. Place one hand under the base and the other hand on the arm.
Label the arm and base. Make sure that the microscope is away from the
edge of the table and that the electrical cord is on the table so that it
can't be accidentally caught and pull off the microscope. Uncover the
microscope and turn on the light source.
10. How should a microscope be carried?
22
11. Where should the scope be placed on the counter and what
should be done with the electrical cord?
To use a microscope, you need to place a slide or a specimen on the
stage. Label the stage and color it light green. You should make sure
that the slide on the specimen is sitting over the hole in the stage. Stage
clips hold the slide in place on the stage. The mirror or light source,
under the stage, will reflect the light source you are using to light up your
specimen. Label and color the light source or mirror violet. For safety
reasons, you should never use a microscope in direct sunlight. This could
hurt your eyes. Locate the diaphragm directly under the stage. This may
be a rotating wheel with different size holes or a lever that moves back
and forth. Label and color the diaphragm dark purple. While looking
through the eyepiece of your microscope at your specimen, adjust the
diaphragm to get the right amount of light coming through the
microscope.
12. Where are slides placed on a microscope?
13. The ________________ under the stage is used to adjust
the amount of light. (Hint: not the light)
Place a microscope slide with your specimen on the stage under the
stage clips to hold the slide in place. Label the stage clips. Look
through the eyepiece to see the specimen. If your microscope has more
than one objective lens, start with the low power objective to get the
clearest and largest view of the specimen. To focus on low power, raise
the stage all the way to the top using the coarse adjustment knob
(larger). Look through the microscope at your specimen and turn the
coarse adjustment knob until the image is clear. Remember that you
always need to keep both eyes open while looking into the microscope,
23
because this will help you to avoid a painful condition called eyestrain.
After the image is clear on the lowest power, turn the nosepiece to the
next highest power and focus the image using the fine adjustment knob
(smaller). Label and color the fine adjustment knob black. Label the
coarse adjustment knob. Once you are finished with your microscope,
remove the slide, return the scope to low power, and turn off the light.
14. What holds the slide on the stage?
15. What object and knob do you start with when focusing your
scope?
16. When do you use the fine adjustment?
Label and Color the Parts of both microscopes!

Using the Compound Microscope
Objective: During this lab you are going to be using the compound
microscope to examine sixteen slides of various specimens.
Procedure: Underline what you need to record.
1) Properly prepare to use the microscope (see next page).
2) Place one slide on the stage and observe it under low power. Then
observe the specimen under medium power and then under high power.
3) Record the name of the specimen in one of the drawing boxes. (6pts)
4) Record the best magnification for observing the specimen. (6pts)
5) Record the total magnification (eyepiece magnification x objective
magnification). (6pts)
6) Make a scale drawing using the magnification power your group found
to be best. (6pts)
7) Color the drawing. (6pts)
8) Repeat steps 1-8 using a different slide.
9) Circle your 5 best illustrations.
32
Steps to Using a Microscope
1) Turn on the light source.
2) Set the microscope to the low power objective.
3) Turn the coarse focus adjustment to get the stage as far away from the body
tube as it can be.
4) Place a slide on the stage and gently secure the slide with the stage clips.
5) Make sure that the specimen to be viewed is over the hole in the stage.
6) While looking through the eyepiece, slowly turn the coarse focus adjustment
until the specimen becomes clear within the field of view. It is very important that
you have patience while you are trying to find the specimen. Work slowly and
carefully and you will be successful.
7) Use the fine focus adjustment to maximize the clarity of the specimen.
8) Adjust the diaphragm to allow the desired amount of light onto the stage.
Brighter is not always better.
9) If you decide it is necessary, switch to the medium power objective. Do not
touch the focus knobs before you switch objectives. After, you switch objectives,
you may have to adjust the focus slightly.
10) If you decide it is necessary, switch to the high power objective. Do not touch
the focus knobs before you switch objectives. After, you switch objectives, you
may have to adjust the focus slightly.
- Remember, never go directly to high power from low power. Use medium
power first.
- Be VERY careful when using high power. If you focus carelessly or too
quickly, you may punch the objective through the slide.
***Other microscope tips***
- Remember, when you move the slide on the stage, the image moves the opposite way! - Never touch the eyepiece or objectives with your fingers. You may get dirt on them or smudge them, making it difficult to get a clear image of your specimen.
33
- Don’t touch the light source (if you have one instead of a mirror). It can get very hot.
- Act maturely around the microscopes. Remember, they are the most expensive piece of equipment we will use this year.
