Complete GCSE Physics lesson on Reflection & Refraction for AQA, Edexcel & OCR – 43 editable slides + differentiated worksheets with full answers. Why does a straw look broken in a glass of water, and why can you see your face in a window at night?

Lesson 3 of the P6 Waves 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. Covers the required practical: reflection and refraction (Physics only).

What’s included

• 43-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: State the law of reflection and draw a reflection ray diagram. Describe what happens to a ray entering and leaving a glass block.
• Silver: Explain specular and diffuse reflection. Explain refraction as a change in speed.
• Gold: (HT) Use wave front diagrams to explain refraction. Describe and evaluate the required practical.
