A class is performing an experiment to keep an ice cube solid as long as possible.
Which student's actions could be a source of error in this experiment?
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.
If Angelina waited until the next day to observe and record how long the ice cube took to melt she wouldn't be able to know how long the ice cube took to melt because she wasn't there while the ice cube was melting.
