1. A study is being done to test the affects of habitat space on the size of fish populations. Different sized aquariums are set up with six goldfish in each one. Over a period of six months, the fish are fed the same type and amount of food. The aquariums are equally maintained and cleaned throughout the experiment. The temperature of the water is kept constant. At the end of the experiment the number of surviving fish are surveyed.
A. Independent Variable: Habitat Space (Different sized aquariums are tested)
B. Dependent Variable: Size of Fish Populations (The number of surviving fish are surveyed)
C. Controlled Variables/Constants: Type of food, amount of food, equal maintenance and cleaning, water temperature
D. Experimental Controls/Control Groups: There are no control groups in this experiment.
