vae as they develop into maturity. Without
food and oxygen, the shrimp cannot develop
and will die. Mature brine shrimp are known
as Artemia Salina.

Note: Using an eyedropper with just the right
pressure to get a desired amount of liquid
onto a slide can be harder than it looks. Take
out a clean slide and practice squeezing a
drop of water onto the slide until you feel
comfortable that you can control the size of
the drop that you’re squeezing out.

4. Observe the life cycle of the shrimp as they

grow: the dried eggs, the hatching eggs, the
developing larvae, and finally, the mature
shrimp.

5. The mature shrimp may be fed to fish in an

aquarium if you so wish. However, first
remove the shrimp from the brine solution
and place them into fresh water. An increase
in salt may harm the fish in the aquarium.

Make Your Own Slides

It’s so easy to make slides that the variety of
slides you can create will be limited only by your
own imagination.

A section of  almost any material can be placed
on a slide and observed with a microscope. All
you need is the proper equipment and a little
patience, and you’ll be making slides in no time.

Everything you need for the experiments in this
booklet can be found in this kit or your home
(make sure to ask a parent first before you bor-
row any of his or her items, such as the measur-
ing cup). Locate the follow items:

• Scissors

•   Paper towels

• Petroleum jelly

•   A measuring cup

• Natural, uncolored toothpicks 
• 2 or 3 small bottle caps 
•  Wide mouth jar and lid
• 3 or 4 paper cups, or any small containers 

which can be discarded after use.

Next, set up your work area....the kitchen table

TIP: Don’t always
assume that
increasing magnifi-
cation will produce
the best image for
viewing.

Each time you
increase in magni-
fication, the
amount of light
decreases, and the
section of the
image you are able
to view also
decreases. This is
desirable for some
specimens, but not
for others. 

Experiment
observing with all
three objectives for
all specimens until
you get a feel for
magnification lev-
els.
