IB DP Chemistry: S1.1 – S3.2 Companion Notes Bundle – Editable PowerPoints & Revision Notes 2026

This bundle provides teaching notes and editable PowerPoint files for IB DP Chemistry Topics S1.1 to S3.2, aligned with the IB Chemistry 2025 syllabus. The materials are designed to help teachers organise lesson content and provide students with structured notes for revision. The IB Chemistry course is organised around two core ideas: structure and reactivity, with topics designed to explain how the structure of matter determines chemical behaviour and reactions. This bundle covers the Structure section of the syllabus, which introduces the models used to explain the nature of matter, bonding, and classification of substances. **Topics Included** Structure 1 – Models of the Particulate Nature of Matter S1.1 Nature of the Atom S1.2 The Nuclear Atom S1.3 Electron Configuration S1.4 Counting Particles by Mass (The Mole) S1.5 Ideal Gases Structure 2 – Models of Bonding and Structure S2.1 The Ionic Model S2.2 The Covalent Model S2.3 The Metallic Model S2.4 From Models to Materials Structure 3 – Classification of Matter S3.1 The Periodic Table S3.2 Functional Groups These topics introduce key ideas such as atomic structure, bonding models, periodic trends, organic functional groups, and the mole concept, which form the foundation for later topics in IB Chemistry. **What’s Included** Teaching notes for each topic (PDF format) Editable PowerPoint versions of the notes Content organised according to the IB Chemistry 2025 syllabus Structured explanations designed for lesson planning and revision The notes can be used as teacher reference material, student study notes, or revision summaries. **Important Note About the PowerPoint Files** The PowerPoint files are not classroom-ready presentations. They are simply editable versions of the teaching notes provided in slide format. The slides contain the same information as the PDFs and are intended for teachers to adapt, modify, or reorganise when preparing their own classroom presentations. **Typical Uses** Teachers commonly use this bundle to: organise lessons for IB Chemistry Structure topics provide structured topic notes for students adapt slides into their own presentations support revision and exam preparation This bundle provides a complete set of structured teaching notes and editable materials for IB Chemistry Topics S1.1–S3.2, helping teachers organise the first major section of the IB Chemistry course.
