Let's melt some chocolate!

Melting Chocolate


Lots of chocolate is stored on shelves in shops. If the shop is too warm will the chocolate melt? If you hold a piece of chocolate in your hand too long it will melt, but do all types of chocolate melt at the same temperature? Plain, milk and white chocolate have different percentages of cocoa solids, which gives it a different chemical makeup. Different brands of chocolate also have different amounts of cocoa solids. Does this affect its melting point? In this experiment, students investigated the melting point of different types of chocolate. The investigation gave them an opportunity to develop investigative skills and learn comparative testing.
