Pearson Edexcel iGCSE Chemistry 4XCH1 | Separating Techniques | Complete Lesson

Complete ready-to-teach lesson for Pearson Edexcel International GCSE Chemistry (9–1) Modular 4XCH1, covering the key experimental techniques used to separate mixtures.

This fully editable PowerPoint lesson is designed for the Pearson Edexcel International GCSE Chemistry (9–1) Modular specification – 4XCH1.

Students develop their understanding of how different mixtures can be separated and, importantly, learn to select and explain the correct separation technique for a given mixture.

The lesson covers filtration, crystallisation, simple distillation and fractional distillation, alongside the key terminology students need when answering examination questions.

Students will learn to:

• Describe how filtration is used to separate an insoluble solid from a liquid
• Understand the terms filtrate and residue
• Explain how crystallisation can be used to obtain a dissolved solid from a solution
• Describe simple distillation and identify the distillate
• Explain how fractional distillation separates mixtures of liquids
• Select an appropriate separation technique for different mixtures
• Use the terms mixture, solvent, solute, residue and distillate accurately
• Apply their understanding to examination-style questions

The resource includes:

• Clear learning objective and success criteria
• Retrieval / Do Now activities
• Key vocabulary
• Step-by-step explanations of separation techniques
• Filtration
• Crystallisation
• Simple distillation
• Fractional distillation
• Scientific apparatus and experimental applications
• Checkpoint questions
• Structured student practice
• Independent application
• Exam-style questioning
• Answers / opportunities for self-assessment

The lesson is designed to move students from recognising each experimental technique to explaining how it works and selecting the correct technique for an unfamiliar mixture.

Suitable for first teaching, consolidation, intervention, revision or cover.
