Reflection: Real World Applications North, South, or Middle? - Section 6: Evaluate

 

I have included a student's design of a crane that she made.  At first look, her design looks flawed but the rubber part of the crane is meant to be behind the car and the magnets would set down on the car.  However, she doesn't describe which part of the magnet would be used and/or why she would use a certain part.  You can see (in red) I asked her to be more specific.

Objective: SWBAT discover that the poles of the magnet are stronger than the middle of the magnet.

Big Idea: Do magnets have core strength? Today your students will learn that a magnets middle is not as strong as you might think and the poles offer the greatest strength.
