A 4-step lesson. Step 1: 'When light hits a smooth surface, it bounces off in a predictable way. This is reflection. Key terms: Incident ray (incoming light), Reflected ray (outgoing light), Normal (perpendicular to surface at point of incidence), Point of incidence (where ray hits).' Step 2: 'First
