IGCSE Physics: Conduction | Edexcel Modular | Unit 3 | L3

This lesson covers spec point 3.6 — describing how thermal energy is
transferred by conduction, and explaining why metals conduct better than
non-metals.

PowerPoint includes:
• Retrieval starter reviewing energy stores and transfer methods from L1–L2
• Direct Instruction (I Do) — conduction mechanism explained through particle
vibration; delocalised electrons introduced as the reason metals conduct
faster; good conductors and poor conductors (insulators) identified with
everyday examples; common misconception addressed (particles do not move —
only energy is transferred); electron video animation referenced
• Guided Practice (We Do) — teacher demonstration using metal rods, drawing
pins and petroleum jelly; students predict order, observe and record results
in a simple table; questions link observations to the mechanism
• Independent Practice (You Do) — activity sheet with exam-style questions
• Review and Reflect — MCQs and exit ticket

Activity Sheet includes:
• 9 exam-style questions progressing from defining conduction and stating why
metals conduct better, through mechanism explanations, to real-life
application contexts including saucepans, ceramic mugs, polar bears and gases
• Practical results table included for the metal rod demonstration
• Full mark scheme for teacher use
