Explanation:
Detailed explanation-1: -A controlled variable (or a constant) is something that is kept the same throughout the experiment. As you pointed out, one controlled variable in your experiment is the amount of material put on the ice cubes. Another one is the refrigerator in which the ice cubes are kept during the experiment.
Detailed explanation-2: -An independent variable is the variable you manipulate or vary in an experimental study to explore its effects. It’s called “independent” because it’s not influenced by any other variables in the study.
