Indicators - KS3 Activate lesson

A full 1 hour lesson designed for a mixed ability year 7 class.
This is the second lesson in “Chapter 4 - Acids and Alkalis” 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 includes a practical demo (a magic trick with “water” into “wine”) and a class practical activity (using litmus paper to test different household solutions).

From this lesson, students should be able to:

• Determine whether a solution is acidic or alkaline, given its colour in indicator
• Describe the colour changes that occurs when red litmus paper and blue litmus paper are added to acidic, alkaline or neutral solutions

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
