Acids and alkalis - KS3 Activate lesson

A full 1 hour lesson designed for a mixed ability year 7 class introducing them to acids and alkalis.
This is an introduction lesson to “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.

From this lesson, students should be able to:

• Know that alkalis are the chemical opposites of acids
• Give examples of common acidic and alkaline solutions
• Describe the hazards of using acids and alkalis
• State how to control the risks of using acids and alkalis
• Compare concentrated and dilute 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
