NEW AQA Physics (2016) - Transformers

This lesson is designed for the NEW AQA Physics GCSE, particularly the ‘Electromagnetism’ SoW.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience

The lesson begins with an introduction to transformers, the role of step-up and step-down transformers are outlined, as well as a description of the everyday uses of transformers. The next slide goes into more detail on how transformers are used within the national grid network. After the introduction, students can then complete a fill-in-the-blank task to summarise what they have learned so far. This task can be marked using the answers provided.

In the next part of the lesson, students are shown a detailed diagram of a transformer and the components it is comprised of. Then, students will watch a video which will run through how a transformer works. Students can watch this and answer a list of questions, which are provided. Then, students can assess their work using the answers provided.

Next, students will follow the investigation worksheet provided to set up a model transformer and complete a few tests to observe whether factors such as the number of turns of wire around the core, or the core material itself, has an effect on the transformer. Students observations can be noted down in their books, and after the investigation the results can be discussed as a class. On the next slide there is a summary of results that students hopefully found by completing this experiment.

Students can then complete an activity whereby they will need to place the sentences in the correct order to describe the action of a transformer, this can be marked using the mark scheme. Lastly, students will be given a worksheet which includes exam-style questions on the topic of transformers. The mark scheme is included in the resources too, so students can either self-assess or peer-assess their work.

The plenary task requires students to write a message based upon what they have learned today.

All resources are included. Thanks for looking, if you have any questions please let me know at swyftresources@gmail.com.
