The purpose of the crossed-out wheelie bin symbol is to
remind us that most electrical product and batteries
contain trace elements which could be harmful to our
environment and therefore our health. We must all be
careful to dispose of them responsibly in a specifically designated way
– either using a collection scheme or into the correctly labelled civic
amenity (NOT into general waste) – this will help your local authority to
arrange to recycle or dispose of them in the appropriate manner.
To be used under
the direct supervision
of an adult.

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 facial tissue.
2. If you are not going to use your
microscope for a week or more, remove
the two batteries that power the
illuminator.
3. Protect your microscope from dust and
moisture by always storing it in its box.

1) First read all the important battery
information on page 6 before you
start. Then turn the microscope
over. Insert two AA alkaline
batteries in the base of the
microscope. In order to remove the
bottom cover of the microscope
you will need a Philips head
screwdriver. Insert the batteries as
shown, making sure that the (+)
and (-) terninals are properly
identified. Replace the bottom
cover and reinsert the screw. Do
not over-tighten.
2) Place the microscope on a flat
surface near a bright light, or in
the daytime or a window. Locate
the mirror and adjust the angle so
that when you look into the
eyepiece you see a bright circle of
light. Do not point mirror towards
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.
Getting Started

3) Once you can see a bright light
circle 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 magnifyng powers of
25X, 50X and 100X
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.
8) Trying using one of the coloured
filters, as they can improve the
image of particular specimens.
IMPORTANT: Wash your hands before
and after every project using warm
water and soap. Also wash any of the
tools and accessories that have been
used to prepare specimens. Be
careful when handling the slides and
slide covers. Make sure an adult
knows what you are doing and is
available to help you.

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.
Cloth fibres, pollen, dust or salt
crystals will be easy to see and make
good samples for beginners to
observe.
If the sample is very thin and clear a
drop of dye may make details show
more clearly. Methylene blue dye (not
included) can be obtained from an
aquarium supply store. You can
transfer a drop of dye from the bottle
to your slide with the pipette.

Cross-sections of stems,
roots and pieces of leaves are
really interesting under the
microscope. When any kind of
cutting is involved, adult
supervision is essential.
3. Pick up your sample with the
tweezers and put it on the centre
section of the slide. Add one drop
of water or, if needed, you can now
add a drop of dye/food colouring
using your pipette.
Use your tweezers and the vials to
collect very small specimens from
your garden or home. Items that are
good to look at under a microscope
are pieces of bath sponge, leaves,
plant roots, flower stems, sand, dirt,
fabric fibres, salt and seeds.
Collecting Specimens
1. Wipe a blank slide clean, as dirt or
grease may affect the viewing of
your specimen.
2. Prepare a thin sample. You may
have to ask an adult to slice
something for you, as knives and
scissors can be sharp.
Making A Temporary Slide
CAUTION!
DYES AND FOOD
COLOURING CAN STAIN.
ALWAYS FOLLOW THE SAFETY
INSTRUCTIONS ON DYE AND FOOD
COLOURING BOTTLES. WE
RECOMMEND THAT CHILDREN WEAR
OVERALLS AND/OR OLD CLOTHES AND
THAT YOU COVER FURNISHINGS,
CARPETS AND WORK SURFACES.
ALWAYS FOLLOW THE SAFETY
INSTRUCTIONS ON DYE BOTTLES.
WHEN USING DYES,
ADULT SUPERVISION IS
ESSENTIAL.
You can also try a little food
colouring to see if that works on
your specimen. Try mixing up our
own colours using different food
colours, an empty vial and the
stirring rod included in the set.
How To Prepare
A Slide
Remember they must be thin enough
and small enough so that the light can
shine through and all around them up
through the hole of the slide. Solid
objects are not good for viewing with
your microscope.
1. Start with a clean slide and slide
cover. Make sure your hands are
clean and dry when handling the
slide covers.
2. Follow Steps 2 and 3 as before.
3. Before placing the slide cover over
your specimen add several drops
of transparent glue (not included).
Caution! Always follow the safety
instructions on glue bottles.
Making A Permanent Slide
– Only adults should replace batteries.
– Do not mix battery types or old and
new batteries.
– Do not use rechargeable batteries.
– Non-rechargeable batteries are not
to be recharged.
– Batteries are to be inserted with the
correct polarity.
– Do not short-circuit the supply
terminals.
– Remove exhausted batteries from
the toy.
Important Information – Safe Battery Usage
4. Place the slide cover gently over
the sample and gently squeeze
out any air bubbles.
5. Place your new slide in a safe
place and let it dry for a day before
you observe it under the
microscope.
We have also supplied labels for
your slides so you can name
specimens for future reference.
4. Gently place a slide cover
(see-through plastic label) over the
sample, being careful not to allow
in any air bubbles.
5. Remove any excess water or
dye/food colouring with a piece of
paper towel (not included) by
pressing it down gently over the
slide cover.
6. Observe your slide.
– When the toy is not in use, remove
batteries to prevent possible
leakage.
– Use only recommended or
equivalent battery types.
– Do not dispose of
batteries in fire:
batteries may
explode or
leak.
