Fish food A claims it can help fish grow bigger than fish food B. You create an experiment that has two bowls of fish. Both bowls have the same water, amount of water, light, and the same amount of fish in each bowl. You measure the fish before you begin with a ruler. You will feed fish bowl 1 food A and fish bowl 2 food B for one month and measure again at the end of the month. The length of the fish is the ________.
