Sample Question
Students studied a species of fish. They wanted to find out if these 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 26°C and another fish in a tank at 22°C. 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. What was the independent variable?

The amount of food given to each fish

The percent change in mass of the fish

The starting mass of the fish

The temperature of the water
