This lesson is designed for the NEW AQA Trilogy Physics GCSE, particularly the 'Electricity’ SoW.
 
The lesson begins with a recap on the calculations that students have learned so far in this topic, students are asked to ‘Think > Pair > Share’ their ideas about the calculation needed to work out the energy transferred to an appliance and the power supplied to an appliance. The answers can then be revealed and students will need to complete a set of questions on a worksheet, this task can be self-assessed using the mark scheme provided.
 
Next, students will watch a video on ‘efficiency’ and whilst watching they will need to answer a set of questions, this work can then be self-assessed using the answers provided. Next, pupils will need to rearrange the equation for efficiency in order to work out the output power of an appliance and using this they will answer a set of questions. The mark scheme for the first part of the questions are included in the PowerPoint so students can assess their own work.
 
Pupils will now be given a set of problems to work through, using the efficiency calculations they have just learned, if they finish the questions on the PowerPoint slide there is a separate worksheet of problems that pupils can work their way through. The mark scheme for the first set of questions is included in the PowerPoint for pupils to self-assess their work.
 
Next, students will be shown how electrical appliances lose waste energy, from this information students will need to summarise using a fill-in-the-blank task. Again, the answers for this task is included in the PowerPoint for students to either peer or self-asses their work.
The plenary task is an anagram challenge, pupils will have to unscramble a 6 words which all relate to the ‘Electricity’ topic.
 
All resources are included at the end of the presentation. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)
