  1. Welcome students to this lesson and encourage several of the students to introduce themselves to each other.
  2. Investigation – Teacher introduces students to the historical debate of light behaving as a wave or as a particle. The experimental evidence provided from Young’s double slit experiment and Einstein’s photoelectric effect is examined, compared and its implications discussed.
  3. Reflection – Teachers stage a debate taking a side and present the experimental evidence for either model of light. Students respond with questions to clarify their ideas.
  4. Investigation – Teacher introduces the construct of energy level diagrams. See the key ideas covered in Prezi L4.2 Energy level diagrams. Resources
  5. Reflection – Teacher discusses the purpose of the short quiz to help consolidate understanding. Resources
