PURPOSE

The purpose of this experiment was to determine the effect of different amounts of fertilizer on the survival rate of brine shrimp.

I became interested in this idea last year when I did an experiment on the effect of oil on brine shrimp and wondered if fertilizers would affect brine shrimp. I have always been interested in fish and marine life.

The information gained from this experiment could show farmers that synthetic fertilizers are harmful to our environment and that they should consider natural fertilizers.

HYPOTHESIS

My hypothesis was that as the amount of fertilizer in the water increased, the survival rate of the brine shrimp would decrease.

I based my hypothesis on the book Animal Care from Protozoa to Small Mammals, which stated that brine shrimp could digest small amounts of certain chemicals.

EXPERIMENT DESIGN

The constants in this study were:
• The amount of brine shrimp in each test group
• The containers the shrimp are in
• The amount of salinity in the water
• The age of the brine shrimp
• The type of water (well water)
• The type of fertilizer

The manipulated variable was the amount of fertilizer in the water.

The responding variable was the survival rate of the brine shrimp.

To measure the responding variable, I looked into the jars and when there was no movement in the jars, then all the shrimp were dead.
