Module 1 is "Properties of Matter" and it includes flame tests of different ionic solutions of metals, and spectral evidence supporting the Bohr model of the atom.
I suppose you could ask a student to recount a first-hand investigation of flame test for potassium ions and copper ions.
Recall the flame colours (1 mark), account for the difference in the flame colours (1 mark), then describe how this evidence supports the essential features of the Bohr model with a diagram of the Bohr model (3 marks).
