So, no salt came in my Salt Things of Science unit. But that’s okay — I think most people can track that down if they wanted to share this unit with a classroom.

Apparently though, salt was presented in this unit in a number of forms (you can read about the different types included in the booklet below).

This unit exemplifies an aspect I like about many of the Things of Science units — it takes a simple and narrow subject, salt in this case, but then gives you history, details about the process of creating it, mining it, and even manages to surprise you with things you did not know. So while salt isn’t particularly “sexy”, you’ll learn a great deal about this common but important chemical.

Let’s hear it for their wonderfully researched booklets:
