Alysha wants to test the effect of different materials on the melting rate of ice. 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, Alysha calculates the final mass of each piece of ice to determine which melted fastest. What are the independent and dependent variables in Alysha’s experiment?
The dependent variable is the mass of the ice, and the independent variable is the type of cover material.
