GETTING STARTED

Open the box and carefully remove the microscope placing one hand around the microscope arm and one

under the base. Place on a ﬂat, sturdy surface.

1. Remove the plastic dust cap from the eyepiece (E).

2. Unscrew at least one screw holding in the rubber cover on the base (N) and install the two AA batteries

(not included) See Fig. 2

CAUTION: Take care to install the batteries in the correct orientation. Follow battery manufacturer’s precautions.

Do not install batteries backwards, or mix new and used batteries. Do not mix alkaline, standard (carbon-zinc),

or rechargeable batteries.

3. You are now ready to use your microscope!

OBSERVING

1. Lower the stage (K). Then rotate the objective

nosepiece (H) until the shortest objective (100X)

is over the stage opening as shown in Fig. 3.

2. Place a specimen of your choice on a slide (A)

and place the slide under the stage clips (J).

Position the specimen over the Stage opening.

3. Look through the eyepiece (E) and slowly

turn the focus knob (G) until the specimen

comes into focus.

4. Adjust the mirror or bottom illuminator (M)

to change the amount of light shining

through the specimen to optimize the image.

5. To increase the magniﬁcation, lower the

stage once again and rotate the nosepiece to

line up either the 600X or 1200X Objective.

HELPFUL TIPS

•Always make sure to lower the stage

before rotating the nosepiece to change the

objective power. This will ensure the objective

will not be damaged by contacting the stage.

•The view through the eyepiece will appear

upside down and reversed from left to right.

Take this into consideration when moving

the specimen slide around on the stage.

• Do not always assume that increasing

magniﬁcation will produce the best image for

viewing. Each time you increase the magniﬁcation,

the amount of light decreases, and the section

of the image you are able to view also decreases.

Experiment observing with all three objectives

for all specimens until you get a feel for the

magniﬁcation levels.

CAUTION: When ﬁnished observing using the light bulb illuminator, be sure to ﬂip the Illuminator over

180°, turning off the lamp ensuring a long life of the bulb.

FUN OBSERVATIONS

1. Filter Wheel: Locate the filter wheel (L) on the stage of the microscope. The filter wheel has

7 positions. There are 4 color filters (Red, Yellow, Blue and Green) and 3 aperture filters

(9mm, 6mm and 3mm DIA). It’s fun to see how the image will change with each filter.

2. Make Your Own Slides: It is easy to make slides! A section of almost any material can be placed on

a slide and observed with a microscope. Your kit includes some of the items you will need, but you

will also need to gather the following typical household items:

• Scissors

• Petroleum jelly

• Natural uncolored toothpicks

• A few small bottle caps

• A wide mouth jar with a lid

• Paper cups, or similar small disposable container

• Paper towels

• Measuring cup

• Plastic dropper

• Scalpel

• Tweezers

Setup your work area on a ﬂat open space, like a desktop. Label 3 cups as “Clean”, “Flush” and “Waste”.

Fill the “Flush” cup with clean water. You are now ready to ﬁnd a specimen. Here is a suggestion for a

simple ﬁrst slide - Crystals.

TIP: Start thinking like a scientist as you perform your experiments. Observe carefully, take notes,

and keep your equipment and work environment clean. Experiments work best with clean and

uncontaminated equipment.

3. Seeing Crystals: One of the easiest slides to make is a Crystal slide. Here’s how it’s done:

a. Use your measuring cup to measure one or two ounces of hot (not boiling) water and pour it into a

clean cup.

b. Slowly add as much table salt to the water as will dissolve. Stir continuously while pouring.

c. Use your plastic dropper to place one or two drops of the salt solution onto a clean slide as shown

in Figure 4.

d. Set the slide aside and allow it to dry completely.

e. Clean your tools, using the “Flush” cup.

f. When the slide is completely dried, it

should be covered in a white substance.

Now place the slide on the microscope

stage and center it over the hole in

the stage.

g. Flip the illuminator over to turn on

the light bulb. Set the objective to the

shortest. Look through the microscope

eyepiece and focus in on the

specimen. You should see crystals!

h. Experiment with different objectives and note the changes.

i. Try other salts and sugars in the same manner to create other crystal slides!

4. Creating Smears:

a. Using a scalpel, gently scrape off small shavings from the surface of a freshly cut potato.

b. Smear the shavings onto a clean slide as shown in Figure 5.

c. This creates a very thin specimen that is ready to view under the microscope.

5. Preparing a Mount: Preparing a

mount refers to larger objects like

the petal of a plant or an ant leg.

a. Dip your scalpel in some clean water

and make a smear across a clean slide.

b. Use your tweezers to place a portion

of an insect wing, or other part, on

the slide.

c. Attach a cover slide (D) over the specimen and place the slide onto the microscope stage,

align and focus.

6. Life Under Glass:

a. Fill the wide mouthed jar with fresh water.

b. Drop a handful of grass and a pinch or two of dirt into the water.

c. Put the lid on the jar and place it in an area that will get moderate sunlight.

d. Let it stand for 3-4 days.

e. After 5 days, it is time to examine the water.

f. Make a specimen slide by using a clean slide and petroleum jelly.

g. Use a toothpick to make a ring with the petroleum jelly on the slide surface.

h. The ring should be smaller than a cover slip and half as thick as the slide thickness.

i. Put a drop of the jar water inside the ring.

j. Using the lowest power on the microscope (shortest objective), observe the specimen.

k. Take note of any microbial movement in the water.

l. Have fun and write down your observations.

CARING FOR YOUR MICROSCOPE: Your microscope is a precision optical instrument and when treated

with care, should provide years of use. Here are a few tips to keep your microscope in top shape:

• Always carry the microscope with two hands.

• Always remove slides from the stage before putting the microscope away.

• Cover the microscope or store it back in the box when not in use.

• Use lens cleaning tissue ONLY when cleaning the lenses.

• Never allow the objective lenses to touch the slide or the stage.

• Remove the batteries before storing the microscope for extended periods of time

(30 days or longer).
