Thermal Processing of Bobby Pins: Interactive Science Lesson 8

In our eighth interactive science lesson, teach students how the thermal treatment of a normal steel bobby pin can influence its mechanical properties, especially strength, ductility, and deflection.
This is an instructional video for the demonstration and lab activity “Thermal Processing of Bobby Pins” from the Materials Science Classroom Kit produced by The American Ceramic Society and The Ceramic and Glass Industry Foundation. The learning objective for this lesson is to show the difference that processing, especially thermal processing, can have on the properties of a material.
The Materials Science Classroom Kit is appropriate for grades 7-12.
