PHYSICS HTS LESSON PLAN
ICSE Class 8 – Reflection of Light
Class:
8
Topic:
Reflection of Light – Curved Mirrors
Learning Outcomes
- Differentiate between concave and convex mirrors.
- Label all parts of a curved mirror correctly.
- Draw ray diagrams for concave and convex mirrors.
- Predict image nature and size from object position.
- Prepare a systematic table for exam answers.
- Solve reasoning-based questions and puzzles.
Procedure
- The introduction begins with real curved mirrors
- Students observe how images appear smaller, larger, or same
- Explanation of concave and convex mirrors using board diagrams.
- Introduction of key terms with labeled diagrams.
- Step-by-step explanation of all ray diagrams for concave mirror:
- Infinity → Point-sized image at F
- Beyond C → Real, inverted, smaller between C and F
- At C → Same size, real and inverted
- Between C and F → Enlarged, real and inverted
- At F → Image at infinity
- Between F and P → Virtual, erect, enlarged
- Convex mirror ray diagrams explained: always virtual, erect, diminished.
- The demonstration of how to prepare an easy table for theory exams.
- Short discussion of important textbook questions.
- Display of mindmap summarising the entire chapter.
- Puzzle-solving and verbal reasoning exercises.
Activities
Activity: Observation of Image Variations
Students observe how a concave mirror magnifies when object is near and inverts when far away

Activity: Step-by-Step Ray Diagram Practice
Using rulers, students
Using rulers, students
to draw ray diagrams for both concave and convex mirrors.
Activity: Image Table Building
Students prepare a combined table for object position, image position, image nature, and image size.
Students prepare a combined table for object position, image position, image nature, and image size.
