A pair of GCSE Chemistry Lessons for Triple Science covering electrochemical cells and associated half equations.

Lesson 1: What are Electrochemical Cells?

Lesson Objectives:

• Describe what an electrochemical cell is and what we use it for
• Describe how to make an electrochemical cell
• Identify factors which affect the size of the voltage produced by an electrochemical cell

This lesson contains:

• Lesson powerpoint
• Student practical investigation
• Teacher notes on how to deliver lesson slides/content and answers

Lesson 2: How do Electrochemical Cells Work?

Lesson Objectives:

• Recall the definitions for oxidation and reduction
• Identify which elements are oxidised and reduced in an electrochemical cell
• (H) – write half equations for oxidation and reduction taking place in electrochemical cells
• Explain why alkaline/non-rechargeable batteries eventually stop working

This lesson contains:

• Lesson powerpoint, containing animation about how electrochemical cells produce electrical current and the reactions that take place within it
• Student exam questions (23 marks worth) from AQA syllabus with mark scheme
• Teacher notes on how to deliver lesson slides/content and answers
