Install the filter as described above and turn the

light source (

U, Fig. 1) until it turns on. Set it so

it shines through the filter. Take a blank slide and

place a few grains of salt or sugar on it. Rotate

the filter and see how the filtered light enhances

the image of the salt or sugar.

The Brine Shrimp Hatchery

Brine shrimp are tiny crustaceans that are ideal

for study with a microscope. Crustaceans are

sea creatures with hard shells and antennae.

Crabs and lobsters are perhaps the most well-

known crustaceans. Brine shrimp are the major

part of the diet of many sea creatures. The word

brine means water containing noticeable

amounts of salt. Brine shrimp are salt water

creatures.

Your microscope kit comes supplied with sea

salt , brine shrimp eggs (

G, Fig. 1) and a shrimp

hatchery (M, Fig. 1). The brine shrimp eggs

included with this set are dried and will remain

alive for up to five years if stored in a cool, dry

place.

Perform the following procedure to hatch the

brine shrimp eggs:

1. To hatch the eggs, first prepare a brine solu-

tion. Pour the entire contents of the vial con-

taining the sea salt (

G, Fig. 1) into a quart of

tap water. Add the brine shrimp eggs into the

solution. Allow the solution to stand at room

temperature (70° - 80°F or 21° - 26°C) for 24

to 48 hours and the eggs will hatch into nau-

plius larvae (this is the first stage of develop-

ment after leaving the eggs).

2. Place some of the larvae into one of the com-

partments of the shrimp hatchery (

M, Fig. 1).

3. Place some fresh brine solution in another

compartment. Add a small amount of yeast to

this new solution. Then, using the eyedropper

(

N, Fig. 1), transfer some of the larvae into

this compartment as well. The yeast will

serve as food and produce oxygen for the lar-

NOTE: Use the

color filter espe-

cially when look-

ing at clear or dim

specimens.
