Question

Bailey wants to find out which frozen solid melts the fastest: soda, ice, or orange juice. She pours
each of the three liquids into the empty cubes of an ice tray, and then places the ice tray in the freezer
overnight. The next day, she pulls the ice tray out and sets each cube on its own plate. She then waits
and watches for them to melt. When the last part of the frozen liquid melts, she records the time.
■ Independent variable: ■ Dependent variable: ■ Control: ■ Constants:

Answer 1

Independent variable: Type of frozen solid (soda, ice, orange juice)
Dependent variable: Time it takes for the frozen solid to melt completely
Control: The empty cubes in the ice tray (no liquid filled)
Constants: The size of the cubes, the temperature of the room, the type of plate used, the initial temperature of the frozen solids
