Class 6 - Physics Lesson Plan
Chapter 5: Light
Topic:
Understanding Light and Its Properties
Subtopics:
- Rectilinear Propagation of Light
- Applications of Rectilinear Propagation of Light
- Pinhole Camera
- Shadows
Learning Objectives:
- Understand that light travels in a straight line (rectilinear propagation).
- Identify real-world applications of rectilinear propagation.
- Explain the working principle of a pinhole camera.
- Describe the formation of shadows and factors affecting their size and shape.
Procedure:
- Introduce the concept of light and its straight-line motion.
- Demonstrate rectilinear propagation using a torch and cardboards with holes.
- Discuss real-life applications (e.g., shadows, eclipses, periscopes).
- Explain the pinhole camera and its function with a simple demonstration.
- Show how shadows are formed and discuss their properties.
Activities:
- Experiment: Demonstrating rectilinear propagation using a laser/torch and obstacles.
- DIY Pinhole Camera: Students make and test a simple pinhole camera.
- Shadow Experiment: Observing how shadow size changes with light source distance.
- Discussion: Applications of shadows in daily life (sundials, eclipses, etc.).
Skills/Values:
- Observation and experimentation skills.
- Analytical thinking and problem-solving.
- Application of scientific concepts in real life.
Assessment:
- Class participation in discussions and experiments.
- Short quiz on rectilinear propagation, shadows, and pinhole cameras.
- Group presentation on real-world applications of light.
- Homework: Identify and explain shadows observed at different times of the day.
