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.

A-DNA and B-DNA: Comparing Their Historical X-ray Fiber Diffraction Images  Amand A. Lucas
This paper provides a comparative explanation of the structural content of the diffraction diagrams of A-DNA and B-DNA that facilitated the discovery of the double-helical structure of DNA by Watson and Crick in 1953. This analysis is supported a method that simulates both A-DNA and B-DNA X-ray images optically.

Experimental Demonstration of Isomorphism  J. Kamenícek and M. Melichárek
The effect of isomorphism may be demonstrated in two ways, using alums: by preparation of mixed crystals with various ratios of components, and by deposition of the second phase on the surface of the initial crystal. The experiments are described.

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.

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.
