Marine Microorganism Science Fair Projects

Marine science fair projects look at common sources of pollution...

Marine Ecosystems

What are marine ecosystems? They are salt water or brachish environments.

Objectives/Goals

Test the effect of marine paint on the hatching of marine microorganisms surrounding the area where marine paint is found.

Methods/Materials

MATERIALS:
Wooden beads
marine paint (Interlux)
brine shrimp eggs
a petri dish
magnifying glass
100 ml. graduated cylinder
mini scoop to measure eggs
scoop to measure salt
plastic cups with lids
distilled water
Kosher salt
spoon
trays
a permanent marker
ruler

PROCEDURE:
Measure 100 ml. of distilled water in a plastic cup.

Then add 3 scoops of Kosher salt. Mix salt with a plastic spoon until salt dissolves. put a mini scoop of brine shrimp eggs.

Close cup with the plastic lid.

Repeat the proccess until you have 48 cups.

Place 6 cups in each tray. At the end there should be 8 trays full. Then paint 24 wooden beads with marine paint (Interlux).

Add a painted bead to every cup in 4 trays that means 24 cups will have a painted bead and the other 24 cups won't (Control Variable).

After brine shrimp eggs hatch(5th day), mix cup gently with a spoon.

Pour 50 ml. of water, with brine shrimp, into the 100 ml. graduated cylinder. Grab a Petri dish, a ruler, and a marker. With the ruler and the marker draw 2 straight lines to make four equal sections(quadrants). Then, place those 50 ml. of water with brine shrimp from the 100 ml. graduated cylinder into the Petri dish.

Count how many brine shrimp are there in each quadrant. The total for each cup should be the sum of the four quadrants multiplied by three.

Record data for every test in a data table.

Repeat this process until all the cups have been observed. (Don't forget to separate the data of the shrimp exposed to marine paint and the ones not exposed to marine paint).

Results

The results after the testing showed that marine paint affects brine shrimp because the cups that had been exposed to marine paint had a smaller amount of living brine shrimp than the ones not exposed. Therefore the hypothesis was supported.

Conclusions/Discussion

In conclusion the final average of living brine shrimp in the cups exposed to marine paint was 106.95. The average of living brine shrimp in the cups not exposed to marine paint was 187.65. Therefore Marine paint does affect brine shrimp. 3rd party contributor
