Which step of the scientific method is this example-

If the molecular structure of solids is more dense than liquids, then water will decrease in volume when it freezes.

In a study, one tank of goldfish is fed the normal amount of food once a day. A second tank is fed twice a day and a third tank is fed four times a day 6 times a week. The fish's body fat is recorded daily. What is the Independent variable in this experiment?

• The normal fish tank.

• The body fat that is recorded daily.

• The amount of food provided to the fish.

• Feeding fish 6 times a week.
