Fish In A Aquarium
Does the size of an aquarium determine how large the fish will grow?

The size of an aquarium will not affect how large a fish will grow.


 * INCLUDE ALL OF THE FOLLOWING WITH YOUR EXPERIMENTAL DESIGN: ** ** [remember it must be a controlled experiment] ** ** 1. A hypothesis ** ** 2. Explain how to set up the experiment: **
 * ** Brainstorm a list of all the variables that must be kept constant during the experiment: ** How much you feed the fish and what, how cold or warm the water is, and what you put in the tanks like rocks and other fish decorations.
 * ** Include identification of the independent variable: ** The independent variable would be the size of the aquariums.
 * ** The dependent variable: ** The dependent variable would be the fish.
 * ** Identify the control group: ** The control group is the fish in the average sized aquarium.
 * ** Identify the experimental group(s): ** The experimental groups are the fish in the bigger and smaller tanks.
 * 3. Provide enough details for someone else to set up your experiment: ** To set up the experiment you would get 3 of the same fish and put one in a small aquarium one in a big aquarium and one in a average size aquarium. You would have to check the tanks after a while to see which fish is the biggest to get your conclusion.
