Lessons 2: How Does the Size of a Fish Affect its Space Requirements?

Space is a need for fish just like food and oxygen. Some fish require more space than other fish. Is the size of a fish the only factor that impacts its space needs?

Doing the science

  1. Start the Aquarium Sim.
  2. Select the "Fish" option on the left side menu bar, choose "Koi" from the dropdown menu, and click the "Add" button.
  3. Click on "View Status" on the left side menu bar to examine the Space Factor. Record this data.
  4. Add another Koi to the aquarium.
  5. Click on the "View Status" icon on the left side menu bar to examine and record the Space Factor.
  6. Select the "Reset" option from the left-side menu.
  7. 7. Repeat steps 2 – 5 above, only this time choose a different fish. Note how many of the other fish you can fit in the tank before reaching larger Space Factor value than the Koi.

Do You Understand?

  1. Open the "Background" section and select "Fish Database" from the bottom of the list. Note the length of the various fish and their Space Factors. How does the length of a fish affect its space requirement?

  2. Determine the mathematical relationship between fish length and space requirements.
