Answer:
One hypothesis for the experiment is if you increase the water temperature in one fish tank and keep the other tank's temperature constant, and the fish are fed the same amount within both tanks, then the fish in the warmer water will grow faster. Another hypothesis for the experiment could be if fish are in twenty-six degree water, versus twenty-two degree water, then small fish will grow at a faster rate than large fish. One factor that was kept the same in each experimental group was the amount of food during the experiment. This was so the mass could be accurately measured, of each fish. The dependent variable is the fish. They are what is being tested or measured in the experiment. Yes, the date supports both of the hypothesis. The proof is in the table results.
Question:
Students studied a species of fish. They wanted to find out if the fish grow faster in warmer water. The students designed an experiment to determine how different water temperatures affect the growth of the fish.
They placed one fish in a tank at 26oC and another fish in a tank at 22oC. The fish were fed the same amount of food during the experiment. The mass of each fish was recorded at the beginning and at the end of the experiment. The data the students collected is show in the table below.
Analyze the procedure and data from the experiment. In your answer, be sure to:
State a hypothesis for the experiment in the If-Then format.
Identify one factor that was kept the same in each experimental group. Explain why.
Identify the dependent variable
Explain whether or not the data supports the hypothesis.
