- 2. Identify two properties of sound and how they are observed.
- 3. Explain one application of sound (echo, sonar, music).
- 4. Give one example each of conduction, convection, and radiation.
- 5. Explain two applications of heat transfer.
- 6. Consult your coach where necessary.
Evidence to Submit:
- • Sound observations.
- • Heat transfer examples.
- • Application notes.
Submission
Part C: Training Others
Guide a peer on sound and heat transfer.
Guidance:
- • Explain how sound is produced and travels.
- • Discuss sound reflection and applications.
- • Demonstrate the three modes of heat transfer.
Reflection:
- • What did the learner understand well?
- • What needed more explanation?
- • What support do you need from your coach?
