This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Chemical changes and electrolysis’ SoW.
 
The lesson begins with a diagram to show how chemical cells/batteries work by relying upon the differing reactivity of metals. Students will then watch a video and will need to answer a set of questions using the information provided in the video, students can then self-assess their work using the mark scheme provided in the PowerPoint.
 
Students will now need to complete an investigation into the potential difference produced by different chemical cells by following the instructions on the practical sheet provided. Pupils will need to record the results of their investigation and write a conclusion on the practical worksheet.
 
The next task is a ‘Quick Check’ to assess students understanding of what they have learnt so far this lesson, pupils will need to complete a set of questions and they can then self-assess their work using the answers provided in the PowerPoint.
 
The last part of the lesson will focus on fuel cells, students will watch a video and using the information provided they will need to ask a set of questions. The answers to these questions are included in the PowerPoint, so students can check their work once this task is complete.
 
Finally, students will be given a set of information on hydrogen fuel cells which they can read in pairs. Using this information pupils will need to produce a table to sum the advantages and disadvantages of using hydrogen fuel cells as an energy source. Students can then check their work against answers provided in the PowerPoint.
 
The plenary task is for pupils to summarise what they have learnt this lesson in three sentences, using key words from the list provided.
