Description: Many students are unfamiliar with the specifics related to the structure, properties and compositions of steels in common use. This module provides an introduction to iron and steel, and discusses relative strength of products, magnetic properties, crystal structure and introduces stainless steels and other alloy steels. Students learn about iron and steel through discussions, demonstrations and suggested optional activities. Cost is also introduced and related to the increased cost of processing stronger and stronger alloys. Designed for up to one class period, the unit may be adapted for any grade level between 10th and introductory college classes. No laboratory is needed and optional activities investigate objects in the classroom as well as objects at home, if desired.
