A biology class wanted to study the effect of different materials on the melting rate of ice. They
placed pieces of ice, each with a mass of 10g, onto trays. Group 1 was covered in plastic, group 2
was covered in paper, group 3 was covered in aluminum, and group 4 remained uncovered.
Each piece of ice was allowed to melt for 15 minutes. Then final mass of the ice, minus the
melted water, was
recorded at the end of the experiment.
What is the dependent variable in this experiment?
Choose 1 answer:
The starting mass of the ice
The type of covering material
