Types of Chemical Reaction — Interactive Lesson (Ages 11–14)

Rusting roofing sheets, burning charcoal and fizzing powders are all chemical reactions. This 18-slide interactive lesson on chemical reactions takes pupils from first ideas to exam-style explanations, with 10 self-marking activities and nothing to prepare beforehand.

Teaching Types of Chemical Reaction in KS3 Science

Pupils tell chemical changes from physical changes, recognise the signs of a reaction and write word equations with reactants and products. They describe oxidation, rusting, combustion and thermal decomposition with everyday examples, and explain how painting, oiling and galvanising prevent rust.

What Pupils Will Learn

• Tell the difference between chemical and physical changes.
• Recognise the signs that a chemical reaction has happened.
• Write word equations for reactions.
• Describe oxidation, combustion and thermal decomposition.
• Explain how rusting can be prevented.
