The pH scale - KS3 Activate lesson

A full 1 hour lesson designed for a mixed ability year 7 class.
This is the 3rd 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 class practical, where students test common household substances with universal indicator solution.
It also includes a printable worksheet.

From this lesson, students should be able to:

• Identify acids, alkalis and neutral solutions on the pH scale
• Describe the colour change of universal indicator in strong acids, weak acids, neutral solutions, weak alkalis, and strong alkalis

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
