No. of Periods: 6

Define reflection of light and identify reflecting surfaces.
State and explain the two laws of reflection.
Draw and label incident ray, reflected ray, and normal.
Describe characteristics of images formed by a plane mirror.
Explain lateral inversion with real-life examples
Relate reflection to daily applications like mirrors, periscopes, and kaleidoscopes.

Introduction / Engagement:
Activity Show students a plane mirror and ask them to observe their image. Display curved mirrors (concave and convex) to demonstrate differences. Use two plane mirrors at angles-) to show multiple images.
Concept Building: Define reflection of light and introduce key terms: incident ray, reflected ray, normal, angle of incidence, angle of reflection.
Demonstration: Verify the law of reflection (∠i = ∠r) using a torch, mirror, and protractor. Draw labeled ray diagrams on the board.
Discussion: Explain images formed by a plane mirror (virtual, erect, same size, equidistant). Demonstrate lateral inversion with words like “SCIENCE”. Discuss real-life applications.

Mirror Observation: Students observe and describe image characteristics in a plane mirror.
Law Verification: Use mirror and pins protractor to measure and verify ∠i = ∠r.
Lateral Inversion: Students write words and see how they appear reversed in the mirror.
Interactive Rainbow Mindmap: Concepts are color-coded for easy revision:

Oral & Written: Define reflection, state laws, describe plane mirror images, explain lateral inversion, draw labeled ray diagrams.
