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 exeperiment]
1. A hypothesis: The tank size does not matter because the fish can grow in a regular sized tank with less space.
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 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.
  • include identification of the independent variable: The indepenend varaible is the size of the tank that the fish will grow in.
  • the dependent variable: The dependent variable is the size of the fish.
  • identify the control group: The control group is the regular size tank. (10 gal.)
  • identify the experimental group(s): The experimental group is the tanks that are the different sizes.
  • 3. Provide enough details for someone else to set up your experiment: There are 10 fish in the three fish tanks. Tank A is the standered size fish tank. Which is ten gallons. Tank B is a five gallon ,and tank C is 15 gallons. They all have puffer fish in them. All of the puffer fish in each tank are males. The tempature of each tank should stay the same through out the experiment. The puffer fish will get feed every night. They get the same amount of food every night. Another thing you need to do is measure each fish every night after you feed them. Do this for a week. Make sure you write down all the measurements.
