Making movies

Want to look at stuff that

? You've
come to the right page.
Choosing your
specimens
Your Digital Blue QX3
™
Computer
Microscope came with two
containment dishes. What can you put
in them? Well, if you've got an
aquarium, how about fish food? Live
fish food.
You can view and take
movies of tubifex worms and brine
shrimp, which are live fish foods. And,
green
how about some of that
stuff
growing on the glass? It's called
algae
and is a simple plant.
Even if you don't have fish to feed, you
can grow brine shrimp just for fun. Or
you can buy some at the pet store.
Once you've got some living brine
shrimp, use your eyedropper to suck
tiny
up a few of the
shrimp
and put
them into a
containment dish
to watch and
record them. Use
low magnification
with bottom light.

It's important to prepare your
sample in another room, away from the

computer.
Bring the
sample to the
microscope after it's
ready. This prevents accidents that
could damage the microscope or
your computer.
Choosing the
magnification
The size of your specimen is important.
To get the most fun out of your QX3
microscope remember this simple guide:
At low magnification, you're seeing
an area about the size of a
thumbtack or a pencil eraser.
At medium magnification, you're
looking at the head of a pin.
At high magnification, you're viewing
an area the size of a pencil tip.
It takes a lot of patience and a little
good luck to capture a good image of
something that's moving around.
The higher the magnification, the more
light you need to see clearly and the
more careful you'll have to be when
focusing and moving your specimen.

a counter under the Record button

Watch out,
Kids!
Be extra careful
when handling
samples that can
spill on electrical
components. Water
a movie,
and electricity don't
mix. Unless you're
careful, you might
hurt yourself or
others and damage
your microscope
or computer.
