Conservation of mass - KS3 Activate lesson

Reactions topic, KS3 Activate (Chemistry)

This unit of work contains seven 1-hour lesson resources designed for a mixed ability year 7 class. This unit follows "Chapter 3 - Reactions” from Activate 1, Chemistry. However, it would be suitable for any KS3 curriculum studying chemistry. This unit of work is designed to be engaging and interactive, with plenty of practical demonstrations and teacher models. There are a couple of class practicals too which come with risk assessments and full, chunked instructions. The lessons are designed so that they can be delivered by any member of staff, regardless of whether chemistry is their specialism. They are also suitable for students working outside the classroom, e.g. in isolation. The lessons should be delivered in this order: 1. Chemical reactions 2. Word equations 3. Oxidation reactions 4. Decomposition reactions 5. Using ratios 6. Conservation of mass 7. Endothermic and exothermic All of my lesson resources contain: * A 5-in-5 retrieval-style starter * An interesting lesson hook, careers link, or retrieval practice to start the lesson * Teacher input slides with dual coding and reduced cognitive load * Teacher models * Regular ‘check for understanding’ slides, such as hand signals quizzes * Regular student independent practice slides, with optional scaffolds, challenges and answer slides * A plenary task
