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 microscopicmacroscopicsymbolic 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.

Empirical Formulas and the Solid State: A Proposal  William B. Jensen
This brief article calls attention to the failure of most introductory textbooks to point out explicitly the fact that nonmolecular solids do not have molecular formulas and suggests some practical remedies for improving textbook coverage of this subject. The inadequacies of the terms "empirical formula" and "molecular formula" are also discussed, and the terms "relative compositional formula" and "absolute compositional formula" are proposed as more appropriate alternatives.

An Inexpensive Kit for Constructing Models of Crystals  Michael Laing
This simple kit comprises five trays, each of 25 square wells, and a lid. It can be used to construct primitive cubic, FCC, BCC, diamond, zinc blende, NaCl, CsCl, rutile, fluorite, perovskite structures. The trays are square tissue culture Petri dishes (multiwell plates). Atoms are represented by glass marbles.

Solid state chemistry: Taught as a comprehensive university course for chemistry students  Boldyreva, Elena V.
While the importance of solid state chemistry for both fundamental chemical science and for modern technology is recognized, there are hardly any comprehensive courses offered for non-specialist students. This author relates her experience in offering such a course.

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.

Recent history of the notion of a chemical species  Bulloff, Jack J.
Quantum and nuclear chemistry have challenged the doctrine that chemical elements are homogeneous entities while studies of the structure and stoichiometry of solids invite a change in our ideas of definite proportions in chemical combinations.
