Exploring Solid-State Structure and Physical Properties: A Molecular and Crystal Model Exercise Thomas H. Bindel
This laboratory allows students to examine relationships among the microscopicmacroscopicsymbolic levels using crystalline mineral samples and corresponding crystal models. The exercise also reinforces Lewis dot structures, VSEPR theory, and the identification of molecular and coordination geometries.

Stuffed Derivatives of Close-Packed Structures Bodie E. Douglas
Examines a variety of stuffed silica crystal structures in terms of the close-packing of one set of atoms or ions (P sites) with other atoms or ions in tetrahedral (T) or octahedral (O) sites and filled or partially filled layers in the regular pattern, PTOT.

Direct visualization of Bragg diffraction with a He-Ne laser and an ordered suspension of charged microspheres Spencer, Bertrand H.; Zare, Richard N.
Bragg diffraction from colloidal crystals proves to be an excellent teaching tool. Only modest equipment and lab skill are needed to produce a diffraction pattern to provide students with an in-depth understanding of what ordered structure is and how it can be probed by diffraction techniques.

How to use crystallographic information in teaching first-year chemistry Bevan, D. J. M.; Taylor, M. R.; Rossi, M.
These authors describe material appropriate for inclusion in a first-year chemistry lecture course. This article stresses how basic chemical principles have been derived from crystallographic results. A potential instructor need not have crystallographic training to incorporate these lectures.

The teaching of crystal geometry in the introductory course Livingston, R. L.
It is the purpose of this paper to outline an approach to the teaching of crystal structure at the elementary level that will prepare the student for more advanced work in this field or that could be used as the beginning in a more advanced course.
