Chocolate in Lewis Class...but not to eat!

Date: 26th Sep 2024 @ 4:43pm

Everyone was extremely excited for our next science lesson, exploring states of matter and how they can change from one state to another when heated or cooled. 

We discussed different ways we could heat a solid to melt it...microwave, oven, hair dryer, the sun - very sensible suggestions. We instead used fire (a tealight candle to be exact). Carefully, everyone observed the effect that the heat from the flame had on two squares of chocolate placed above in a foil tray. Despite the disappointment at not being able to consume the treat, everyone was fascinated with the melting process and intrigued to discover the temperature of the chocolate. This was measured by thermometers; initially the chocolate began melting at 40 degrees celsius, however some temperatures reached up to 90 degrees celsius. At that point, we could see (and smell) that the chocolate was burning. Flames extinguished, we each drew up the experiment in our books and wrote explanations and conclusions.

Well done to everyone in Lewis today for being so sensible throughout our experiment and I hope you enjoyed it!
