KS3 ~ Year 8 ~ Electromagnets

This lesson is designed for the KS3 Year 8 Science course, specifically the P2 1.1 unit on ‘Electricity & Magnetism’.

The lesson begins with an introduction to electromagnets, students are shown a diagram of an electromagnet and told how an electromagnet is made; students can make a note of these details in their books.

This follows into a video, students will watch the video and whilst watching will be given a series of questions to answer. Once this task is complete, students can then self-assess their work against the mark scheme that is provided.

Students will now be asked to consider what might affect the strength of an electromagnet, students can be given a few minutes to come up with their ideas in pairs before feeding back into a class discussion. Students will now complete an investigation into whether the following two factors - number of coils of wire & voltage - will affect the strength of an electromagnet. Students should follow the instructions provided on the PowerPoint presentation and complete the table of results in their books.

Once the investigation has been completed, students will complete a ‘Quick Check’ task in their books to assess their knowledge of what they have learned this lesson. The mark scheme for this is included for students to self-assess their work once it is complete.

Lastly, students will complete a ‘Copy and Correct’ task whereby students will need to copy a paragraph of information into their books, correcting any of the information that they seem to be erroneous. This task can also be checked against the answers provided on the PowerPoint presentation.

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 :)
