How to use your new microscope:
There’s a whole tiny universe around you ready to be explored! All you need is your microscope, and a zest for adventure. Your microscope is an instrument with special lenses that make very small objects appear much larger. There are millions of tiny living organisms that can be seen in amazing detail through your microscope.
Your microscope set contains the following parts. Check your microscope kit and make sure that you have all of the parts listed below. Put a check mark in the box beside each item you find.
1 die-cast microscope (a)
1 scalpel (b)
1 spatula (c)
1 tweezers (d)
4 collecting vials (e)
1 test tube with cap (f)

make the sample look very big. This microscope can make things look 300 times, 600 times, or even 1,200 times bigger than you can see them with your own eyes.
b) Scalpel – A scalpel is a sharp blade that is used to cut very thin pieces of material so you can look at them with your microscope.
c) Spatula – The spatula has a large flat blade, but it is not as sharp as the scalpel. It is used for scraping off bits of material for testing and to push down on soft samples to mash them flat.
d) Tweezers – The tweezers are like little pinchers. They are used to pick up small samples and to handle samples that you don’t want to touch with your hands – like slimy mold!
e) Collecting vials – These are little plastic bottles with tight-fitting lids. They are used to carry your samples from the place you collected them to the place you have your microscope set up.
f) Test tube with cap – This thin, clear tube is used to hold liquid samples when you want to see if anything is happening, like when a sample changes color.
g) Petri dish – This is a round, flat dish with a clear cover. It is used to grow and observe samples such as molds.
h) Pipette – This is a soft plastic tube with a squeeze bulb on one end that you use to transfer a drop or two of liquid to a slide for examination.
i) Prepared slides – These are slides with professionally prepared samples on them for you to examine.
j) Blank slides – These are clear slides for you to use in preparing your own subjects for examination.
k) Slide labels – These are little pieces of paper with sticky backs. You can stick them on your slides and record information, such as the name of the sample, or when the sample was prepared.
l) Slide covers – These are little circles or squares made of thin, clear plastic. They are used to cover very small samples on a slide. When they are clean and dry they stick to the glass slide with a static electricity charge.
m) Crystallized red dye and crystallized blue dye – In your set you will find two small plastic bottles. One has a small amount of red powder in it and one has a small amount of blue powder. Add enough warm water to half fill these plastic bottles. Place the lids on and make sure they are tight. Shake well to make a supply of dye. If you add a drop of red or blue dye to a sample, like a thin slice of onion, you will be able to see the cells much more clearly.
n) Stirring rod – Use this rod to mix liquids until they are well blended. An example is when you mix salt in water.
o) Magnifying glass – This is useful for taking a close look at a sample before you examine it under the high-power magnification of your microscope.
p) Measuring graduate – This plastic cup is marked with measuring lines so that you can accurately measure quantities of liquids in your experiments.

q) Spare light bulb – This spare bulb will replace the one in the illuminator lamp when it eventually wears out.
r) Camera adapter – This adapter lets you attach a single use camera or a digital camera to the microscope so you can make photographs or digital images of the exciting subjects you will see.
s) Projection device – With the projection device you can study the microscope image on a small screen; or you can project an image onto a white wall or other white surface. You can even project the image down onto a piece of white paper. This way you can trace the outline of the sample you are studying and make your own drawing. You can save these drawings in an album, or you can use them in school projects.
Parts of Your Microscope:
E
G
I
J
A. Eyepiece – The eyepiece is where you look into the microscope. It is a small magnifying lens that
collects the image projected by the objective lens.
B. Body tube – This is the main tube of the microscope. The image from the sample travels up this tube to the eyepiece.
C. Focusing knobs – Turn these knobs very slowly to bring the image of your sample into focus so you can see it sharply.
D. Revolving lens turret – The turret holds the three objective lenses. To change the lenses, rotate the turret slowly until each lens clicks into position.
E. Objective lenses – These lenses give three different magnifying powers when working with the eyepiece lens. They make samples look 300 times (300X), 600 times (600X) or 1,200 times (1,200X) bigger than you can see them with your eyes alone.

F. Arm – This curved piece is the “backbone” of the microscope and holds everything together. You can tilt and adjust the angle of this arm to set the most comfortable viewing position.
G. Stage – The stage is the flat platform that supports your slides for viewing.
H. Slide clips – The two clips on the stage hold your slide in position so that it doesn’t move around while you are looking at it.
I. Mirror – The mirror aims light from a bright source, like a window or a table lamp, upward through
the slide you are studying so you can see it more clearly.
J. Electric illuminator – When there is not enough light available for the mirror to fully illuminate your slide, you can turn the mirror over and use the bright electric illuminator bulb as your light source.
K. Base (battery compartment) – The base provides a solid support for your microscope. It also holds the batteries for the electric illuminator. See the first section in ‘Getting Started’ for instructions on installing and changing the batteries.
Helpful Hints
1) The most important parts of your microscope are the lenses. Handle them with care. If the lenses are dirty or dusty you can clean them with a soft cotton cloth or a special lens-cleaning tissue. Do not wipe them with a finger or a regular facial tissue.
2) Always store your microscope in its protective storage case.
Getting Started
1) You will need to insert two AA alkaline batteries in the base of the microscope. First, you must
remove the rubber antiskid bottom cover to access the battery compartment. You will need to use a Phillips-head (+) screwdriver to remove the two screws on this bottom cover. Once the cover is removed, insert the batteries as shown, making sure that the (+) and (-) terminals are properly aligned. Replace the cover and re-insert the screws. Do not overtighten.
2) Place the microscope on a flat surface near a bright light or window. There is no need to insert a
slide just yet. Adjust the angle of the mirror so that when you look into the eyepiece you see a bright circle of light. Do not point the mirror toward the sun as eye damage may result. If there is no bright light available, or if the room lighting is poor you can use the microscope’s electric illuminator. To turn on the illuminator flip the mirror over so that the light bulb is aimed upward. The light will come on by itself. Look through the eyepiece and adjust the angle of the light until you see a bright circle.

3) Once you can see a bright circle of light in the eyepiece your microscope is ready for use.
4) Choose one of the prepared sample slides from your set. Place it under the two spring clips on top of the stage.
5) Next, choose the magnifying power you want to use. Your microscope can provide magnifying powers of 300X, 600X, and 1,200X. Remember that the longer objective lenses provide the higher powers. Most observing is done at low-power, and we suggest that you start with the 300X setting.
6) To change the magnifying strength turn the revolving lens turret until you hear a click.

7) Turn the focusing knob until the objective lens is almost touching the slide. Don’t let the lens touch the slide as you may break the slide and damage the lens. Now look through the eyepiece and slowly turn the focusing knob back until you see the sample clearly.
How to make your own prepared slides
Samples for examination should be very thin so that light can pass through them. If the sample is too thick it will appear dark in the microscope.
There are thousands of common items around the house and in the yard that can provide interesting samples. To name just a few you could start with cloth fibers, hair, plant or vegetable leaves, grass, paper, onion skin, pollen, dust, salt crystals, and even water!
If the sample is very thin and lacks color, a drop of red or blue dye can help make details show more clearly. To prepare the dyes in your set add enough warm water to half fill the dye bottles. Replace the lids tightly and shake well until the dye crystals are all dissolved. You can transfer a drop of dye from the bottle to your slide with the pipette.
Always be careful when using the dyes as they can stain clothing, furniture, or carpets.
Making a Temporary Slide
A) Start with a clean blank slide. Clean slides are important. If your slide is dusty or dirty, you
should clean it with a soft cloth, so that you do not also magnify dirt or dust along with the sample you want to view. This can be distracting and even confusing!
B) Prepare a thin sample. You may have to slice it with the scalpel. Always be very careful. You
should ask for adult help when using sharp objects.
C) Pick up your sample with the tweezers and put it on the center section of the slide. Add one
drop of water. To enhance viewing you may add a drop of dye instead of water.
D) Gently place a slide cover over the sample, being careful not to allow any air bubbles in.
E) Remove any excess water or dye with a piece of paper towel by pressing it down gently over
the slide cover.
F) Now you can observe your slide.

How to Use the Camera Adapter
The camera adapter can hold a personal digital camera or a single use camera loaded with ISO400 type film. To position the adapter, remove the microscope eyepiece and place the camera adapter over the focusing tube. Place the camera on the camera adapter base plate so that the camera lens is directly over the hole in the base plate. Then place the “U” shaped camera holder over the camera and push it down until the camera is held tightly.
If your digital camera has a video display screen you can preview the image for positioning and focus sharpness. If your camera does not have this screen you may have to experiment with different focus positions and checking the results. Depending on the camera design you may not need to make any adjustment. Take your first pictures with the objective lens almost touching the glass slide. Measure the position of the focusing tube carefully and keep records of each picture taking focus position. When you find the best position that gives a sharp picture you may want to make a small mark on the focusing tube so that the microscope can be set the same position for the next pictures you take. Your best results will be at the 300X setting.
How to Use the Projection Device
1) Twist the eyepiece counter-clockwise and gently pull up to remove it. Insert the viewer head over the focusing tube.
2) Face the viewer head towards a white wall or a piece of white paper.
3) Turn out the room lights and close any curtains. For best results the room should be dark.
4) Turn on the electric illuminator and place a prepared slide on the stage.
5) Try a distance of 1 to 1.5 meters (3 to 4 feet) from the wall or paper.
6) Adjust the illuminator lamp so that the image is as bright as possible.
7) Carefully adjust the focus until you see a sharp image. You may have to re-adjust the illuminator position.
8) You should now see a clear projected image. If you use a higher magnification you will have to re-focus the microscope.

How to Use the Drawing Device
You can observe the image on the unit’s projection screen, or you can project an enlarged image onto a white surface.
1) Make sure that the plastic viewing screen is in place in the slot on the top of the viewing hood.
2) Adjust the focus and illuminator until you see a clear image on the screen.
3) To see an enlarged image, remove the plastic viewing screen from its slot.
4) Make sure that the microscope is in the upright position.
5) Place a piece of white paper horizontally in front of the base of the microscope.
6) Darken the room and adjust the angle of the viewer hood mirror until you see the image projected on the white paper. Adjust the focus and illuminator lamp position for the best result.
IMPORTANT SUGGESTIONS: When you are using the drawing device or the projection device you must be in a darkened room. You will see the brightest views in a very dark room. Make sure that the batteries are fresh and all lenses and mirrors are clean. Before studying your slides in the dark, give your eyes a few minutes to adjust.
When using the projection device you may get some “light spill.” This is unwanted light that comes directly from the illuminator or bounces off of reflective surfaces. This unwanted light can overpower the projected image, making it very hard to see. If light spill is affecting your projected image you might try placing your hand in front of the illuminator to block this extra light.

History of the Microscope
During the late Middle Ages (around A.D. 1200 to 1450), the growing demand for eyeglasses led to experimentation with lenses and making small things appear larger. As a result of this experimentation, the first microscope was created (probably in Holland in the late 16th century—the Dutch were masters at the craft of magnification).
The first microscopes were operated with only one lens—then the compound microscope was invented in the 1590s, which used two or more lenses to magnify objects even more. Among the most famous people to use a compound microscope was Robert Hooke of England. During the 1600s, Hooke observed and recorded the miniscule parts of nature previously unexplored, such as the intricacies of feathers, insects, and even mold. Furthermore, Hooke introduced the concept of cells— the smallest independently functioning part of an organism.
Today scientists use microscopes to aid in the world of medicine, help build better and stronger materials for everyday use, and even discover hidden mysteries about ancient cultures and environments.
One of the most powerful scientific instruments in existence is called the scanning electron microscope (SEM). Instead of magnifying objects using lenses, like your microscope, the SEM focuses a beam of invisible particles called electrons on the object, and collects the electrons as they bounce back. These electrons are then turned into a black-and-white image on a television screen. SEMs can magnify some small objects as many as 100,000 times—that’s about 50 times more powerful than the strongest ordinary compound microscope.
Cells
One subject that’s easy to observe with your microscope is a cell. Both plants and animals have cells. Plant cells (which Robert Hooke identified) have structured walls, and basically serve as mini–food factories. Photosynthesis takes place inside the plat cell. Photosynthesis is the conversion of solar energy into chemical energy (or the production of oxygen and glucose from water and carbon dioxide).
Unlike plant cells, animal cells have a permeable membrane (instead of rigid, structured walls). This permeable membrane—through which certain things can pass—encases a number of even smaller specialized components called organelles. An animal’s body (including yours) is entirely made up of these cells. They range in size and shape, depending on their function and location. Even the cell’s life span varies from type to type—heart muscle cells, cartilage cells (the soft tissue connecting your bones at the joints), and most neurons (brain cells) can never divide, regenerate, or be replaced. On the other hand, liver cells are replaced about every 500 days, cells in your stomach lining about every two days, and skin cells about every one to 34 days.
Check this out! Try taking a toothpick and gently swiping the inside of your cheek. Then take those cells you’ve gathered on the toothpick and make a slide for your microscope. (See “How to make your own prepared slides” on page 6.) What do you see when you observe the slide under magnification?
Now look at the prepared slides included with your microscope. Can you see the rigid walls that plant cells are known for?

Frequently Asked Questions
1) What can I see with my microscope?
You can see thousands of things that are difficult or impossible to see with your eyes. You can see tiny plants and animals. You can observe plant and animal cells. You can see the differences between different plants, different papers, different fibers, and hairs from different people. You can study crystals, rocks, and minerals. The uses for your microscope are practically endless.
2) What is meant by power?
Power is a measure of the seeing ability of your microscope. It is really a short way of saying “magnifying power.” Your microscope has three powers. They are 300X (pronounced “300 times”), 600X, and 1,200X. This means that your microscope can magnify the view of a sample so that it appears 300 times, 600 times, or 1,200 times larger than the way you see it with your own eyes.
3) I look through my microscope and all I see is darkness. Why?
This could be because the mirror or light bulb is not positioned properly to aim light up into your microscope. Or maybe the sample you are looking at is too thick so the light cannot shine through it.
4) All I can see is a partial circle of light. Why?
To see your sample properly, the light source must be centered through the slide to provide the brightest and most even illumination. Try gently moving the mirror or light until you see a full, evenly lit circle while looking through the microscope.
5) I have a very thin sample on my slide, but I can’t see any detail.
First, make sure that the image is in sharp focus by adjusting the focusing knobs. If the problem still exists you should add a drop of red or blue stain to the sample. Stains make hard-to-see objects like plant cells stand out so they can be seen better.
