This set of activities has students using everyday items (batteries, magnets, compasses, iron and paper clips) to reveal the connection between electricity and magnetism.
The electromagnetic force produces both electricity and magnetism.
Students will be able to:
Create a magnetic field with electrical circuits.
By going through a series of hands-on activities, students will experience how electricity and magnetism are related. Students observe the magnetic field around a closed circuit, investigate how electromagnetism can make a working motor, and build a temporary electromagnet by converting electricity into magnetism. This lesson fits nicely into a classroom unit on electricity and magnetism. Ideally, students will already have experience building simple circuits. Since each activity in this lesson builds on the previous one, we recommend delivering them in this order:
Worksheets guide the hands-on activities for students and allow you to assess their developing abilities to make and communicate their observations, analysis and conclusions.
A self-assessment tool is provided for students in three of the activities.
Answer keys are provided.
