Presentation transcript:

Topic: Magnetism Objective: Cover basic foundation of electric magnetics and motors Summary: Students are asked what they know about specific topics and then the instructor fills in gaps or clarifies information. The key to this lesson is having the students make an electromagnet and test it and for the students to determine how to power a motor that lacks part of its housing. Instructor Information

Topic: Magnetism Methodology: ▫ Inquiry and Discussion – in most cases the students are asked to explore the topic before the answer is provided in the presentation Differentiation: Students work in small groups and groups that finish early are given additional tasks as other groups continue to work.
