Instructional Ideas

• Find a video on how to construct a compass and make one in class
• Before finishing the lesson, have the pupils draw what they think the magnetic field of a magnet looks like

Classroom Considerations

• The class should have a basic understanding of magnetic properties and what makes a compass work
• Third of an eight-part series

Pros

• Includes assessment questions to determine the classes' understanding of the concept
• The lesson background contains important information to include in your lecture

Cons

• The lesson plan does not employ an engaging instructional strategy
