Taylor is interested in glacier melt in the arctic. She decides to test the effect of different materials on the melting rate of ice. First she finds the initial mass of four pieces of ice. She then covers three pieces with either tinfoil, plastic wrap, or paper. The fourth piece is left uncovered. After 30 minutes, Taylor calculates the final mass for each piece of ice. What is the dependent variable?
Mass of ice
