Answer 3

[AI-generated answer — Explain Bot]

The independent variable in this investigation is the amount of ice cubes added. This is because the independent variable is the variable that is manipulated or adjusted by the experimenter. In this case, the student is adding different amounts of ice cubes to each sample of water. By changing the amount of ice, the student is able to observe and measure the effect it has on the final temperature of the water after 30 minutes.
