This lesson plan aims to teach students about the different types of reflection through observation, group activities, and discussion. It will help students develop factual, conceptual, procedural, and metacognitive knowledge of regular and diffuse reflection. Regular reflection occurs when light reflects regularly off a smooth surface like a mirror. Diffuse reflection is irregular reflection off a rough surface like a brick. The lesson enables students to recognize and explain the different types of reflection through hands-on activities and examples.
