Why Does Salt Melt Ice?

A Snowy Everyday Example in Engineering

It’s the season of slip-slidin’ away in much of the northern hemisphere, with engineering students among those gingerly making their way across snowy, icy campuses, neighborhoods, and roads.

Why Does Salt Melt Ice?, one of ENGAGE Engineering’s most downloaded lesson plans, is a great way to introduce students to the concept of colligative properties. It’s perfect for use in winter when conditions are icy and treatment of streets and sidewalks is a frequent, and often welcome, occurrence.

Whether you and your students are in a snowy region or watching icy, snowy weather elsewhere on the news, give this easily implemented Everyday Example in Engineering a try and see how your students respond.

The Power of a Well-Timed Everyday Example in Engineering

  • Using examples that are familiar and relevant to students enhances the likelihood that they will be interested in, intuitively understand, and better retain the information they learn.
  • Everyday examples that communicate how engineers help society in both simple and complex ways can create enthusiasm and persistence.
  • E3s are effective among ALL groups of students.
