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 the fastest.
What are the independent and dependent variables in Alysha's experiment?

a) The dependent variable is the type of cover material, and the independent variable is the mass of the ice.
b) The dependent variable is the mass of the ice, and the independent variable is the time the ice takes to melt.
c) The dependent variable is the mass of the ice, and the independent variable is the type of cover material.
d)
The dependent variable is the time the ice takes to melt, and the independent variable is the type of cover material.

Answer:

In the experiment conducted by Alisha to test the effect of different materials on the melting rate of ice, the dependent variable is the mass of the ice, and the independent variable is the type of cover material.

Explanation:

During an investigation or experiment, the dependent variable is the one whose changes will be studied, while the independent variable is able to influence the changes of the dependent variable.

In the case where it is wanted to <u>measure how different cover materials affect the rate of ice melting</u>, the dependent variable is the mass of ice and the independent variable is the coverage material, capable of affecting the time it takes for the ice to melt.
