A full 1 hour lesson designed for a mixed ability year 8 class.
This is the 3rd lesson in “Chapter 2 - Separation techniques" from Activate 2, Chemistry. This lesson is on 'solutions’.
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.
This lesson also contains a practical demonstration complete with an equipment list and chunked method.

From this lesson, students should be able to:

• Define the terms ‘solute’, ‘solvent’ and ‘solution’.
• Identify solutes, solvents and solutions from given examples.
• Describe how to prove that a solute has not ‘disappeared’ when added to a solvent.
• Predict the mass of a solution when given the mass of a solute and solvent.
• Explain what happens when a solute dissolves in a solvent in terms of their particles.

All of my lessons 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 and whiteboard quizzes
• Regular student independent practice slides, with optional scaffolds, challenges and answer slides
• A plenary task
