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 ofall 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: 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.
. 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
