Density - KS3 Activate lesson (Chemistry)

Particles and their behaviour - KS3 Activate TOPIC

This unit of work contains seven 1-hour lesson resources designed for a mixed ability year 7 class. This unit follows "Chapter 1 - Particles and their behaviour” from Activate 1, Chemistry. However, it would be suitable for any KS3 curriculum studying particles, states of matter and changes of state. This unit of work is designed to be engaging and interactive, with plenty of practical demonstrations and teacher models. 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. The particle model 2. Density 3. States of matter 4. Melting and freezing 5. Boiling 6. More changes of state 7. Diffusion 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
