= Does t he 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 **

. Timmy wonders how he can keep his fish alive longer. dr.Mahon suggested to get different sized tanks but get one that is just a regular sized. Timmy filled the tanks 90% of the way full. then
 * hypothesis: if you increase the size of the tank the fish will grow larger and last longer.
 * other variables: how much food you feed the fish, what species of fish,and what kind of food you feed the fish, how much oxygen is in the tank at a time, what kind of water its in ex: saltwater or freshwater,supplies that are put in a tank, how much sun light is applied, the temp. of the water,the health of the fish,how clean the tank is,how often its fed.
 * independent variable: the size of the fish tank
 * dependent variable: the growth of the fish
 * control group: the regular sized tank (10 gal.)
 * experimental group: the XXL, the XL, and the small fish tanks
 * Precedure: first get a XXL,the XL,then the small tanks. then fill all tanks about 90% full. place all 5 fish in the tanks that are 2 years old at the same time. finally ever 30 days measure how larger the fish got in each tank.
