Introduction to the properties of clay minerals
University of Illinois at Chicago
This activity was peer reviewed prior to publication in the Teaching Mineralogy Workbook.
This teaching activity was originally published in: Brady, J., Mogk, D. W., and Perkins, D., (editors), 1997, "Teaching Mineralogy," a workbook published by the Mineralogical Society of America, 406 pp. All teaching activities in this volume received two external peer reviews from mineralogy faculty focused on content and pedagogy, and a final review by the co-editors to comply with the publication standards of the Mineralogical Society of America.

How the activity is situated in the course
This activity is a stand alone exercise. This activity is a stand-alone exercise, but is part of a larger volume of classroom and laboratory activities from "Teaching Mineralogy," a workbook published by the Mineralogical Society of America, Brady, J., Mogk, D. W., and Perkins, D., (editors), 1997,406 pp.
Content/concepts goals for this activity
In this activity students learn about the physical properties of clays.
Higher order thinking skills goals for this activity
Skills developed include the analysis of data and the application of experiments to environmentally relevant problems.
Other skills goals for this activity
Students also learn to work with a partner or a group.
Description of the activity/assignment
This activity explores how clay affects the permeability of sands, the effect of chemical differences of the clay (cation exchange), and how these results may be applied to low-level radioactive waste disposal sites.
Determining whether students have met the goals
Class discussions are used to establish whether students have met the goals.More information about assessment tools and techniques.
