Does the size of an aquarium determine how large the 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 **
 * ** include identification of the independent variable **
 * ** the dependent variable **
 * ** identify the control group **
 * ** identify the experimental group(s) **


 * 3. Provide enough details for someone else to set up your experiment. **

__//**Hypothesis:**//__ My hypothesis is that the size of the tank does not matter the size of the aquarium because I believe that the size of the fish with depend on the health,amount of food the fish get, and how clean the fishes tank is.

__//**Variable that must be kept constant are:**//__ There has to be the same amount of fish in the tank, the fish have to all be the same kind of fish, each tank needs to be cleaned on the same day, time, and the tank needs to be cleaned with the same products, the fish need to be provided with the same food, same amount of food, they also need to have the same amount of things inside the fish tank.


 * //__The Independent Variable:__//** The independent variable is the size of the tank that the fish will be gorwing in.


 * //__The Dependent Variable:__//** The dependent variable is the fish in the tank that are being observed by the scientist.

__//**The Control Group:**//__ The control group is the group that is being run under normal conditions, in this case the control group is the size of a normal tank that is being observed, so tank A.

__//**The Experimental Group:**//__ The eperimental group is the group that the varaible/condition is being dliberately changed, in this case the experimental group(s) are the different sizes of the tank that the fish are in, so tank B, and tank C.


 * //__Details on how to run thi__//** **//__s experiment:__//** You must first get three different sized tanks, secondly get about 51 fish so you can divide the fish into the three tanks with 17 fish in each tank. Make sure all the fish are the same size, same type of fish, the same age, all the fish must be the same in order for this experiment to work. The third step is to cover the bottom of each tank the same way with the same materials. You must also make sure you keep the fish in the same temperature of water and must have the tanks in the same type of location and the fish must be feed the same at the same time. The last step is to feed the fish regularly and observe the fish regularly. They will be measuring how big each fish gets in each of the tanks.
