Part B: Project
Observe wave behavior and light formation with simple examples.
Project Title: Waves and Light Observations
Objective: Demonstrate reflection, refraction, and basic lens effects.
Project Instructions:
- 1. Describe a real example of reflection and refraction of waves.
- 2. Use a simple setup to show refraction of light (e.g., pencil in water).
- 3. Explain diffraction or interference with a daily example.
- 4. Describe how a lens forms images and give one use.
- 5. Consult your coach where necessary.
Evidence to Submit:
- • Wave behavior examples.
- • Light refraction notes.
- • Lens and image formation summary.
Submission
Part C: Training Others
Guide a peer on wave properties and light behavior.
Guidance:
- • Explain reflection, refraction, and diffraction.
- • Demonstrate a light refraction example.
- • Discuss lenses and image formation.
Reflection:
- • What did the learner understand well?
- • What needed more explanation?
- • What support do you need from your coach?
Submission
