Ask students what they think would happen if chocolate was left outside in the sun.
Then perform the experiment testing how long it takes the chocolate to melt. Try this in the shade and in the sun.
After ten minutes look to see if the chocolate is melted, if not record how soft it is.
Discuss as a class the reason why the chocolate has melted.
You can perform this experiment in other ways as well such as recording how long it takes to melt in your mouth.
