Complete GCSE Physics lesson on Specific Latent Heat for AQA, Edexcel & OCR – 42 editable slides + differentiated worksheets with full answers. Why does it take seven times more energy to boil a kettle dry than to melt the same mass of ice?

Lesson 3 of the P3 Particle Model of Matter unit. Suitable for Combined Science (Trilogy) and Triple Physics, Foundation and Higher tiers. Just open and teach – every slide, worksheet and answer is done for you.

What’s included

• 42-slide editable PowerPoint – every word at least 28 pt, so it reads clearly from the back of the room (great for SEN, dyslexia and visual impairment)
• Do Now retrieval starter with answers, a picture hook, I do / we do / you do worked examples, equation cards and clear original diagrams
• Mini-whiteboard quiz, an illustrated hinge question with explained answers, and click-by-click answer reveals
• Exam-style question with mark scheme and sentence starters, 3-2-1 exit ticket, homework and glossary
• Clickable countdown timers and full teacher notes (spec match, 60-minute lesson plan, common misconceptions)
• 6-page differentiated worksheet pack (Word + PDF) – Bronze, Silver and Gold tasks, a stretch challenge, exam question, exit ticket and full answers and mark schemes

Learning objectives

• Bronze: Define specific latent heat. Use E = m × L.
• Silver: Distinguish latent heat of fusion from vaporisation. Distinguish specific latent heat from specific heat capacity.
• Gold: Solve combined heating + change-of-state problems. Describe and evaluate a method to measure L.
