A student predicts that similar ice cubes will melt faster in a microwave than in a pot on the stove. How should this hypothesis be tested?

• Identify and record the temperature of each ice cube before each trial.

• Determine the volume of liquid water made by each ice cube.

• Observe and record the time for each ice cube to completely change to a liquid.

• Measure and compare the volume of the pot and the microwave.
