A. Carey put the ice cube in cold water and recorded the temperature
every 2 minutes as the ice cube melted.
B. Angelina waited until the next day to observe the ice cube and
record how long it took to melt.
C. Jody outlined the ice cube to measure it before it started to melt.
D. Jerrie wrapped the ice cube loosely in several layers of cotton and
aluminum foil.
