1. 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 over night. 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: Soda, ice, or orange juice
Dependent Variable: How fast it melts
Controlled Variable: How long she waits, how much of each is used
