Students wanted to compare how long it takes an ice cube to melt, depending on the temperature around it. So they made four ice cubes of equal size by measuring how much water they poured into the ice cube tray. The next day, they placed each ice cube on a waxy plate. They put one plate in the refrigerator, one outside in the sun, one on the counter under a lamp, and one on a counter with no lamp. After one hour, they measured how much water had melted onto each plate. What is the independent variable in this investigation?

• Ice Cubes

• Where the Waxy Plate was Placed

• Amount of Water Melted

• Boiling Point of the Water
