Where Are the Particles?
Read the diagram, name the state. Read the change, say which way the energy went. Then face the three things the particle model refuses to allow — which is where most people, including adults, lose it.
Three rounds. Round 1 shows you the particles. Round 2 shows you a change. Round 3 shows you nothing and asks what the model forbids.
Teacher Panel
Formative evidence, not a mark. Round 3 is the one to read: Rounds 1 and 2 can be passed by recognising pictures, and Round 3 cannot.
