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 ofall 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.
