Insert the baeries. First stack the
three buon cells on top of one
another, each with its positive end
down. Then insert the stack into the
baery compartment, again
keeping the positive end down.
Done!
Mount the cover. First
hook it onto the closure
knob and then latch it in
on the left side.

Object
DID YOU KNOW?
An instrument that has at least a 40-fold
magnification is called a microscope. Lower levels of
magnification are often called “macroscopic.” Both
words are based on Greek roots. “Mikros” means
small, and “makros” means large. In either case, what
it means is that small things can be seen as if they
were noticeably larger.

Light path
In puing together your microscope, you
assembled the various lenses and their
sleeves into a so-called “optical path.” The
eyepiece lens sits fixed at the upper end. This
is what your eye looks through.
The relay lens can be moved up and down
with the zoom adjustment ring. It lets you
switch between a low level of magnification
(20 times) and high magnification (40 times).
The focus adjustment ring moves the
objective lens. That adjusts the distance from
the object in a way that lets you focus the
image.
Circuit
When you installed the wires and
electronic components, you built a
circuit. From the positive terminal
of the baery compartment, the
red wire goes to the switch and
then to the illumination unit, where
the LED bulb is installed. From the bulb,
the black wire leads to the negative
terminal of the baery compartment.
When baeries are inserted and the
switch is turned on, the circuit is closed.
The current flows from the baeries
through the light, and the LED lights up.
If the switch is pushed again, the circuit
is interrupted. Then the light goes out.

YOU WILL NEED
› Pocket microscope
› Dead insect (from a window sill, for example)
HERE’S HOW
Use your microscope without its stand. Place a
dead insect on the table or another smooth
surface and then position the microscope
over it.
TIP !
There are lots of places where you can find
“bugs” such as insects, spiders, or roly-
polies. Take a look in the corners of the
basement, under boards or rocks in the
garden, or in a lampshade inside a room. Be
sure to have your parents help you.
There are plenty of dead bugs that you will
be able to find. Do not kill any bugs for your
experiments!
BUGS UP CLOSE!
Insects and other bugs possess an
exoskeleton made of chitin. On the surface,
you will often find hairs, scales, or other
structures. The eyes of insects consist of
many individual eyes and are called
compound eyes. On their feet, you can often
see claws or suction disks, and the wings will
have lots of fine veins running through them.
