What is the independent variable when testing the effect of temperature on ice melting?

Answer and explanation

Correct answer: Environmental temperature

Environmental temperature is the factor deliberately changed in this experiment, so it is the independent variable. The time taken for the ice to melt, or the amount of ice melted, may be measured as the dependent variable. Factors such as the size and initial mass of the ice piece should be kept constant. Exam tip: the variable intentionally changed by the experimenter is the independent variable.
