IGCSE Physics — Unit 4: Solids, Liquids and Gases | Complete Unit Resource Pack | Edexcel (Pearson) Modular

This is a fully complete, exam-ready resource pack for Unit 4 of the Pearson Edexcel International GCSE Physics (Modular) specification, covering spec points 4.3–4.14P. Every resource has been built specifically for the modular specification and is ready to use from day one.

What’s included:

8 PowerPoint Lesson Decks — each lesson is structured using the Rosenshine Principles of Instruction, with a clear I Do, We Do, You Do framework embedded throughout. Every lesson opens with a retrieval starter to activate prior knowledge and address misconceptions before new content is introduced. New material is introduced in small steps with clear worked examples (I Do), followed by scaffolded guided practice (We Do), building to independent exam-style practice (You Do). Lessons close with a review and reflect phase to consolidate learning.

8 Student Activity Sheets — one per lesson, covering all spec points including all three core practicals (4.4, 4.11P, 4.14P). Questions use Edexcel command words throughout and are pitched at the full range of ability, including stretch questions. Each sheet includes a full mark scheme.

Student Activity Booklet — all 8 activity sheets compiled into a single print-ready booklet with cover page and contents. Ideal for exercise book replacement or folder inserts.

Mark Scheme Booklet — all mark schemes compiled separately for teacher use.

Revision Guide — a visually rich student revision booklet covering all 8 topics. Each topic includes a concise summary, key equations, a fully worked example and quick check questions. Includes diagrams for particle arrangements, pressure, heating curves and more. Answers included at the back.

End of Unit Assessment — a 45-mark, 50-minute exam-style paper covering the full unit. Includes 5 multiple choice questions, short answer and extended writing questions, a cooling curve graph interpretation question, and answer lines throughout. A full mark scheme is included.

Topics covered:

• Density of regular and irregular objects (4.3 & 4.4)
• Pressure on solids (4.5)
• Pressure in fluids (4.6 & 4.7)
• Particle theory and changes of state (4.8P–4.10P)
• Core practical: investigating change of state / stearic acid cooling curve (4.11P)
• Specific heat capacity (4.12P & 4.13P)
• Core practical: specific heat capacity of aluminium (4.14P)

Designed for: Pearson Edexcel International GCSE Physics (Modular) — 4XPH1, Unit 1. Suitable for Year 10 or Year 11 depending on your scheme of work.

Specification compliance: All resources are checked against the modular specification. No off-spec content (e.g. no percentage error questions). Practical skills are assessed through written questions in line with the examination approach.

Can be used for the linear course too.
