This comprehensive PowerPoint bundle covers S2.4 From Models to Materials for IBDP Chemistry (first examination 2025), linking bonding models to real-world materials and properties. It provides a clear, structured sequence of lessons to help students understand how bonding and structure determine the behaviour and uses of materials.

From models to materials focuses on applying bonding theories (ionic, covalent and metallic) to explain the properties and uses of substances. Rather than treating bonding as separate categories, students explore bonding as a continuum, using tools such as the bonding triangle and electronegativity to predict material behaviour and properties .

This bundle includes 6 fully editable PowerPoint (.pptx) lessons designed for teaching, revision or flipped learning:
• Properties of materials and bonding as a continuum
• The bonding triangle and use of electronegativity to classify substances
• Alloys, including structure, properties and real-world applications
• Introduction to polymers and structure–property relationships
• Addition polymers, including mechanisms and naming
• Condensation polymers (HL extension), including polyesters and polyamides

Each lesson includes retrieval starters, key definitions, worked examples, and exam-style practice questions. Students develop skills in classifying bonding, predicting physical properties (e.g. melting point, conductivity, flexibility), and linking chemistry to applications such as materials design, sustainability and fast fashion.

This resource is ideal for IB teachers delivering both SL and HL content, supporting conceptual understanding while preparing students for exam-style questions and real-world application of chemistry.
