Potassium Metal Is Explosive—Do Not Use It! Andreas Grubelnik, Veronika R. Meyer, Peter Bützer, and Urban W. Schönenberger
The reaction of sodium with water is a spectacular and essential classroom demonstration. Many teachers want to show also the more violent reaction of potassium. We propose not to do so because explosions can happen even before the metal is in contact with water.

Trusty or Rusty? Oxidation Rate of Nails Stephen W. Wright
Students investigate the process of rusting using supermarket chemicals. Steel nails are placed in gelatin and allowed to react with atmospheric oxygen. Ferric ion produced by the oxidation is made visible as a garnet-colored complex formed by the magnesium salicylate in backache tablets. Factors that accelerate or retard the rate of iron oxidation are studied.

The Oxidation of Iron in a Gel Using Consumer Chemicals Stephen W. Wright, Marsha R. Folger, and Ryan P. Quinn
The ferric ion produced by the oxidation of a steel nail in an agar gel is detected with salicylate to give a garnet-red color at the anodic areas where the oxidation of iron occurs.

Memory Metal JCE Editorial Staff
Students compare the properties of nitinol wire to those of waire made from other metals. Using the observed properties of nitinol, students then design (and may make) a toy that relies on nitinol for its operation.

Materials Science Teaching Module as Adjunct to Introductory Chemistry Terry D. Gulden, Kirk P. Norton, Holger H. Streckert, Lawrence D. Woolf, Joseph A. Baron, Shauna C. Brammer, Danine L. Ezell, Roger D. Wynn
A materials science teaching module was developed by a team of scientists and teachers that incorporates aspects of chemistry, physics, materials, and engineering with emphasis on engineering of materials. The level is geared towards high school, but with modification it can be taught at the middle school level. Three general classes of materials are studied, namely metals, ceramics, and polymers.
