Does the size of an aquarium determine how large the fish will grow?


 * 1. A hypothesis: ** The size of the aquarium does determine how big the fish will grow.


 * 2. Explain how to set up the experiment: **
 * ** brainstorm a list of all the variables that must be kept constant during the experiment: ** The temperature of the water, type of fish, age of the fish, type of food, same amount of food, and type of brand of aquarium.
 * ** include identification of the independent variable: ** The different sizes of aquariums.
 * ** the dependent variable: ** The number of fish in this experiment.
 * ** identify the control group: ** The fish in the regular aquarium.
 * ** identify the experimental group(s): ** The fish in the four groups of five


 * 3. Provide enough details for someone else to set up your experiment: ** A scientist wants to know does the size of a aquarium determine how large the fish will grow. The scientist gets 20 fish and puts the fish in to 4 groups of 5. The scientist puts 5 of the fish into a small aquarium,then the next five into a regular aquarium, then the next five into a large aquarium, and the last five in the larger aquarium. Then when 30 days passed he will measure them.
