Titanium, Aluminum or Steel?

This six-page guide from Edmonds Community College outlines a classroom demonstration on the basic differences between metal types and how to test metals. Through a spark test demonstration, students observe the "visible result of the carbon content in steel," the relative lack of carbon in other materials, and the reactivity of titanium metal. This demonstration introduces students to materials science and materials testing concepts. The lesson also includes a discussion or lab to complement the demonstration, and takes fifteen minutes to complete. This guide includes the following sections: Module Objectives and Student Learning Objectives, MatEd Course Competencies Covered, Equipment and Supplies Needed, Curriculum Overview, Module Procedures, and an Evaluation Packet.
