A full 1 hour lesson designed for a mixed ability year 7 class. This is the 5th lesson in “Chapter 1 - Particles and their behaviour” from Activate 1, Chemistry. This lesson is on ‘boiling’. This lesson should be suitable to teach to any KS3 Chemistry class, even by those where chemistry is not their specialism. This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks. From this lesson, students should be able to: Explain what is meant by the term ‘boiling’ Describe what happens to the particles in a liquid when it boils Use given information about a substance’s melting point and boiling point to predict its state at room temperature 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

A full 1 hour lesson designed for a mixed ability year 7 class. This is the 4th lesson in “Chapter 1 - Particles and their behaviour” from Activate 1, Chemistry. This lesson is on ‘melting and freezing’. This lesson should be suitable to teach to any KS3 Chemistry class, even by those where chemistry is not their specialism. This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks. From this lesson, students should be able to: Explain what is meant by the terms ‘melting’, ‘freezing’ and ‘change of state’ To describe what happens to the particles in a substance when it melts or freezes. To state the factor in the particle model that explains why different substances have different melting points Estimate the melting point of a substance from its temperature-time graph 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

A full 1 hour lesson designed for a mixed ability year 7 class. This is the second lesson in “Chapter 1 - Particles and their behaviour” from Activate 1, Chemistry. This lesson should be suitable to teach to any KS3 Chemistry class, even by those where chemistry is not their specialism. This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks. From this lesson, students should be able to: Identify and draw particle diagrams for solids, liquids and gases Describe the arrangement and movement of particles in solids, liquids and gases Use the particle model to explain the properties of solids, liquids and gases (e.g. explain why solids and gases cannot be compressed) 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

A full 1 hour lesson designed for a mixed ability year 7 class. This is the 6th and penultimate lesson in “Chapter 1 - Particles and their behaviour” from Activate 1, Chemistry. This lesson is on ‘more changes in state’. I have chosen to focus this lesson on evaporation and condensation, and not discuss sublimation. This lesson should be suitable to teach to any KS3 Chemistry class, even by those where chemistry is not their specialism. This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks. From this lesson, students should be able to: Explain what is meant by ‘evaporation’ Describe the changes in the arrangement and movement of particles when a liquid evaporates Compare boiling and evaporation Explain what is meant by ‘condensation’ Describe the changes in the arrangement and movement of particles when a liquid condenses 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

A full 1 hour lesson designed for a mixed ability year 7 class. This is the first lesson in “Chapter 1 - Particles and their behaviour” from Activate 1, Chemistry. This lesson should be suitable to teach to any KS3 Chemistry class, even by those where chemistry is not their specialism. This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks. From this lesson, students should be able to: Recall that materials are made up of particles Recall that all particles in a substance are the same Use the particle model to describe the properties of a substance List the four factors that affect the properties of a substance 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

A full 1 hour lesson designed for a mixed ability year 7 class. This is the 7th and final lesson in “Chapter 1 - Particles and their behaviour” from Activate 1, Chemistry. This lesson is on ‘diffusion’. This lesson should be suitable to teach to any KS3 Chemistry class, even by those where chemistry is not their specialism. This lesson (and all lessons in this unit) is designed to be interactive and engaging, with plenty of real world examples and independent tasks. From this lesson, students should be able to: Recall the definition for the key term ‘diffusion’ Explain why diffusion happens in terms of particles Explain how temperature, particle size and state affect the rate of 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
