The ‘What do I already know about my topic?’ sheet was an important step in anchoring the project in the theory about heat transfer covered in previous lessons. It was a clear way of showing that conduction, convection, radiation and evaporation were the factors to be considered.
Collaboration with the library was key. Jenny Toerien identified that the importance of evaporation in heat loss was often misunderstood by pupils. It wasn’t something that was explicitly taught in the topic so we used this as a worked example in the materials to act as a prompt for teachers to show pupils how theory and practice can be linked.
