Magnetic Materials

The design challenge: develop a method to separate steel from aluminum. The first lesson plan in an eight-part series introduces the class to the grand challenge of ciming up with a method to streamline a sorting process at a recycling company. After a class discussion, scholars determine possible solutions to the problem.

Instructional Ideas

  • Invite a steel recycling company representative to come speak to the class
  • Get the class to brainstorm different methods of picking up materials, including non-metalic ones, and determine which ones can be used to separate materials
Classroom Considerations

  • The class should have an understanding of the basic chemical and physical properties of metals
  • The first activity in an eight-part series
Pros

  • The challenge handout comes as a PDF and a doc, so it is editable
  • The resource contains a section devoted to the engineering connection of the lesson
Cons

  • As a stand alone lesson, there is little content other than introducing the challenge
