Melting Moments... Science Failure

This term we have been learning about Melting Moments in Science.  As part of this we conducted an experiment to see whether a whole Freddo Frog would melt quicker, slower or at the same pace as a Freddo broken into pieces.  Unfortunately, as it was such a warm day, they both turned to mush within minutes.  Of course what should have happened is that the small pieces should have melted quicker as their is more surface area for the heat to make contact with.
