A class is performing an experiment to keep an ice cube solid as long as possible.
What students actions could be a source or error in this experiment
A. Jerrie wrapped the ice cube loosely in several layers of cotton and
aluminum foil.
B. Carey put the ice cube in cold water and recorded the temperature
every 2 minutes as the ice cube melted.
C. Jody outlined the ice cube to measure it before it started to melt.
D. Angelina waited until the next day to observe the ice cube and
record how long it took to melt.
