A Demonstration of Refractive Index Matching Using Isopropyl Alcohol and MgF2  Frederick C. Sauls
Isopropyl alcohol and magnesium fluoride have nearly identical refractive indices; thus a chip of MgF2 disappears when immersed in isopropanol.

Introduction to Photolithography: Preparation of Microscale Polymer Silhouettes  Kimberly L. Berkowski, Kyle N. Plunkett, Qing Yu, and Jeffrey S. Moore
In this experiment, a glass microscope slide acts as the microchip. Students can pattern this "microchip" by layering negative photoresist on the slide using a solution containing monomer, crosslinker, photoinitiator, and dye. The students then cover the photoresist with a photomask, which is the negative of a computer-generated image or text printed on transparency film, and illuminate it with UV light. The photoresist in the exposed area polymerizes into a polymer network with a shape dictated by the photomask. The versatility of this technique is exemplified by allowing each student to fabricate virtually any shape imaginable, including his or her silhouette.

Pushing the Rainbow: Frontiers in Color Chemistry; Light and Color in Chemistry; Report on Two American Chemical Society Presidential Events  Nancy S. Gettys
On Sunday March 21, 1999, the 217th ACS National Meeting in Anaheim, California sponsored two Presidential Events, "Pushing the Rainbow: Frontiers in Color Chemistry" and "Light and Color in Chemistry". The events included 10 exceptional and very different speakers who explored various aspects of the importance of light and color in chemistry and chemistry teaching, in other sciences, and in art and human culture.

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.

Rolling happy and unhappy balls and their coefficients of friction   Nicholson, Lois
Writer brings to attention some misinformation a previous author had communicated in an attempt to explain the popular demonstration using "happy" and "unhappy" balls made of Neoprene and Polynorborene.
