From Textiles to Molecules—Teaching about Fibers To Integrate Students' Macro- and Microscale Knowledge of Materials Hannah Margel, Bat-Sheva Eylon, and Zahava Scherz
This article describes a new interdisciplinary learning program for junior high school students based on the science, technology, and society (STS) approach emphasizing a macromicro view and consolidating an understanding of the structures of materials through the context of fibers.

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.

Hands-on Classroom Photolithography Laboratory Module To Explore Nanotechnology Scott J. Stelick, William H. Alger, Jesse S. Laufer, Anna M. Waldron, and Carl A. Batt
Teaching nanotechnology in the high school and undergraduate environment is a challenge given the typical expense of instruments used to create micro- and nano-sized devices. To meet this challenge, a portable optical reduction stepper was designed, fabricated, and optimized for use in classrooms. This unique system was designed to provide a safe, hands-on experience for students to create microscale circuits using photolithography. Students are able to design, fabricate, and test a circuit with dimensions as small as 100 mm.
