IGCSE Physics: Energy Stores and Transfers | Edexcel Modular | Unit 3 | L1

This lesson covers spec points 3.2 and 3.3 — describing energy transfers
involving all eight energy stores and four transfer mechanisms, and applying the
principle of conservation of energy.

PowerPoint includes:
• Retrieval starter reviewing prior knowledge from Units 1 and 2
• Direct Instruction (I Do) — all eight energy stores introduced with examples;
four transfer mechanisms defined (heating, mechanical work, electrical work,
radiation); conservation of energy stated and applied; energy transfer chains
modelled step by step; correct Edexcel language (“transferred to” not
“converted into”) emphasised throughout
• Guided Practice (We Do) — describe the energy transfer in a falling ball;
describe the transfer chain for a battery-powered motor lifting a weight;
calculate wasted energy from a toy car scenario
• Independent Practice (You Do) — activity sheet with exam-style questions
• Review and Reflect — MCQs and exit ticket

Activity Sheet includes:
• 10 exam-style questions progressing from recall (state 8 energy stores,
state conservation of energy) through to multi-step chains and evaluation
(assess a device that claims to output more energy than it receives)
• Real-world contexts including a torch, a toy car and a falling ball
• Full mark scheme for teacher use
