We made a simple, bitter chocolate from cocoa powder, sugar and butter to see what it was like. Our next step will be to add different things in to make our own bar of chocolate.
We did an experiment to see which chocolate would melt first: dark, milk or white. We put a piece of chocolate in it's own foil boat and set it in to a bowl of hot water. It took quite a while, but we discovered that our dark chocolate melted first, then the milk with the white chocolate last.
We also carried out an investigation to see which material makes for the best chocolate bar wrapper. We put a piece of chocolate wrapped in different materials in a ziplock bag along with a piece of onion and left it over night.
The foil made for the best sort of wrapper as it kept out smell and taste. The paper towel was the worst as it absorbed the juice from the onion and the chocolate had a strong smell and taste of the onion.
Having found out where chocolate comes from and where the factories are that turn the cacao into chocolate ready for us to eat, we looked at the history of chocolate. The Mayan and Aztec people who lived around what is now Mexico drank a very bitter chocolate drink or xocolatl.
We made some of our own.
