Answer:

Amount of ice

Explanation:

When we talk about independent variable, we mean that variable in an experiment that is manipulated and its effect on the dependent variable is measured.

In this case, the amount of ice in each water sample determines the temperature of each sample. Hence the amount of ice is the independent variable.
