Complete GCSE Chemistry lesson on Chromatography for AQA, Edexcel & OCR – 40 editable slides + differentiated worksheets with full answers. A ransom note, three suspects, three black pens – how can a strip of paper and some water tell the police who wrote it?

Lesson 2 of the C8 Chemical Analysis unit. Suitable for Combined Science (Trilogy) and Triple Chemistry, Foundation and Higher tiers. Just open and teach – every slide, worksheet and answer is done for you.

What’s included

  • 40-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 hook, I do / we do / you do modelling and clear diagrams
  • Mini-whiteboard quiz, a 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: Describe how to set up paper chromatography and why each step matters. Use a chromatogram to say which dyes are in a mixture.
  • Silver: Explain separation using the stationary and mobile phases. Calculate Rf values and use them to identify substances.
  • Gold: Use chromatography to decide whether a substance is pure; explain the ‘every solvent’ rule. Evaluate the method and suggest improvements.

Specification

  • AQA GCSE Chemistry 8462 / Combined Science Trilogy 8464 – 4.8.1.3
  • Edexcel GCSE Chemistry 1CH0 / Combined Science 1SC0 – matching topic content
  • OCR Gateway Chemistry A J248 / Combined Science A J250 – matching topic content

Key words: chromatography, stationary phase, mobile phase, solvent, start (pencil) line, solvent front, Rf value, chromatogram, pure, soluble

Save money: this lesson is also in the discounted C8 Chemical Analysis complete unit bundle and the full GCSE Chemistry course bundle (C1–C10).

Ideal for KS4 / Year 10 and Year 11 GCSE Chemistry teaching, cover lessons, intervention and revision of chromatography.
