Today, Crew Hamill conducted another exciting experiment to help us to understand that some things can change state. We began by recapping a previous science experiment from Spring term in which we investigated how temperature effects the rate at which ice melts. We discussed this as we were able to identify that ice (which is a solid) melts into water (which is a liquid) if it is heated. If this is then frozen again, it will return to a solid. We then put this to the test in two ways. To begin, we had a look at wax. We discussed that this was a solid and then placed it into a wax burner which provided heat. We then left this, observing it at intervals throughout the lesson to see what happened. The block of wax disappeared before our eyes and turned into a liquid! We then switched the burner off and watched as it slowly cooled and returned to a solid. Whilst this was happening, we worked in mini crews to investigate chocolate. We placed solid chocolate into a bowl and heated it over a pan of boiling water. We watched as the chocolate melted and then placed this melted chocolate into moulds. We left this melted chocolate to cool in the moulds and are excited to see our results tomorrow when we pop the chocolates out!
