Heating Materials

Today in Year six we investigated what happened when we heated various materials. We used a sand bath and candle to help us heat egg, chocolate, butter, wax and bread safely. We observed how the materials changed and discussed whether the changes were reversible or irreversible. We discovered that heating egg and bread causes irreversible changes whilst the chocolate, wax and butter melted. We could get these materials back by leaving them to cool.
