1. Lucas wants to find out which frozen solid melts the fastest: soda, ice or orange juice. He pours each of the three liquids into empty cubes of ice trays, and then places the ice trays in the freezer over night. The next day, he pulls the various types of ice out and sets each cube on its own plate. He then waits and watches for each of them to melt. When the last part of the frozen liquid melts, he records the time. Indenpendent variable: Dependent Variable: Control Variable: Constant(s): Hypothesis:
