A 5-E lesson about electromagnets. Students will do an activity to introduce them to the link between electricity and magnetism. They then test variables that they believe may affect the strength of electromagnets. The “Elaboration” section includes options for either an engineering project or a research project. Background information, and links to a digital model, can be found in the Elaboration section as well. It is recommended that teachers use the “If you have time” suggestions in the lesson plan, as these suggestions offer the best 3-dimensional learning opportunities.
