Energy transfer, forces - KS3 Activate lesson

A full 1 hour lesson designed for a mixed ability year 8 class.
This is the 8th and final lesson in “Chapter 2 - Energy” from Activate 2, Physics. This lesson focuses on work done (titled ‘energy transfer - forces’).
This lesson should be suitable to teach to any KS3 Physics class, even by those where physics 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:

1. Give a definition for the key term ‘work’
2. Identify when work is being done from a range of scenarios
3. To calculate work done using the equation force x distance
4. To explain how simple machines (levers and ramps) allow some forces to have greater effects
5. To explain why a lever is known as a ‘force multiplier’
6. To apply the law of conservation of energy to simple machines

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
