Lesson Plan
Grade: 9 Date: 25/02/2026
Subject: Physics
Lesson Topic: Describe how energy is transferred between stores during events and processes, including examples of transfer by forces (mechanical work done), electrical currents (electrical work done), heating, and by electromagnetic, sound and other waves
Learning Objective/s:
  • Describe how energy is transferred between different stores via mechanical work, electrical currents, heating, and wave phenomena.
  • Explain the formulas used to calculate energy transfer for each mechanism.
  • Apply knowledge to identify the energy stores involved in real‑world examples and predict the resulting energy forms.
Materials Needed:
  • Projector and screen for slides/diagrams
  • Whiteboard and markers
  • Printed worksheet with energy‑store flow chart
  • Simple apparatus: spring, masses, battery‑powered torch, heater element, speaker
  • Calculator for formula calculations
 Introduction:
Begin with a quick demonstration: lift a book onto a shelf while asking students what forms of energy are involved. Recall the law of conservation of energy and link it to today’s success criteria: students will be able to describe and calculate energy transfer across different mechanisms.
Lesson Structure:
  1. Do‑now (5’) – students list as many energy stores as they can on mini‑whiteboards.
  2. Mini‑lecture & concept map (10’) – teacher presents the six transfer mechanisms using the flow‑chart diagram.
  3. Guided practice (15’) – work through example calculations for mechanical work and electrical work in pairs, using the worksheet.
  4. Demonstrations (10’) – spring compression, torch battery, heater, speaker; students identify input and output stores.
  5. Group activity (10’) – each group chooses a real‑world example (e.g., ocean wave) and fills a table showing the energy stores and transfer mechanism.
  6. Check for understanding (5’) – quick quiz via Kahoot or show of hands.
  7. Plenary (5’) – recap key points and address misconceptions.
Conclusion:
Summarise how each mechanism moves energy between specific stores and emphasise the conservation principle. Students complete an exit ticket describing the energy transfer in one example of their choice. For homework, assign a short worksheet to calculate energy transferred in a household appliance.
