Complete Topic 4h: Polymers Edexcel IGCSE Chemistry 9–1 Bundle 7 lessons

Bundle of 7 fully planned lessons and resources for Topic 4h Polymers Edexcel IGCSE 9–1 Double/Separate Chemistry.

Checklist, key terms, definitions, tech guide, revision PowerPoint, coursebook questions and answers included. Perfect for new and experienced teachers, this resource provides an authentic, ready-to-teach unit requiring no additional preparation. All lessons are contained in one PowerPoint with a consistent, clear structure.

Lessons & Key Content:

1. Producing Addition Polymers – recap of addition reactions and testing for alkenes; formation of polymers such as poly(ethene), poly(propene), PVC and PTFE; linking properties (e.g., flexibility, strength, unreactivity) to common uses.

2. Making a Polymer (Slime Practical) – modelling polymer behaviour using slime; understanding cross-linking and how polymer chains affect properties; comparing biodegradable vs non-biodegradable materials.

3. From Polymers to Monomers – identifying repeat units; deducing monomers from polymer structures by reinstating the double bond; practice with common polymers.

4. Disposal of Polymers – evaluating landfill, incineration and recycling; understanding why most addition polymers are non-biodegradable; environmental impact discussions and tasks.
   End-of-Unit Questions (Double Award) – structured practice and review questions.

5. Condensation Polymerisation (Separate Chemistry) – differences between addition and condensation polymerisation; forming polyesters from dicarboxylic acids and diols, releasing small molecules; drawing polymer links.

6. Biopolyesters – definition, environmental advantages, bacterial decomposition; application questions and comparisons.

Each lesson includes starter slides with title, learning goals and tasks, along with key terms, bolded explanations, and content checked against the specification and examination papers. Core practicals or key demonstrations are included where relevant with step-by-step modelling, notes, diagrams and student tasks, blooket and quizzes. The PowerPoint features click-in animations, embedded video links, model questions and answers, and coursebook tasks to support strong conceptual understanding. A technician guide and full lesson list appear on Slide 2 for easy planning.

Notes:
Slide 1 is repeated for TES display purposes.
Lesson starter slide background is black but PowerPoint colour schemes vary throughout.
Separates content is clearly identified
