This reading is self-explanatory, presenting a biographical sketch of Stephanie Kwolek as well as a discussion of the uses and importance of aramid fibers. The science of aramids allows for more discussion of the relationship between molecular structure and macroscopic properties; aramid chains are stiffer and straighter than nylon chains, therefore they make stronger fibers. In addition, the use of aramids in body armor provides a dramatic example of how chemistry has an impact on the real world.

Relevant National Science Education Standards

Science as Inquiry — The nature of science as inquiry and the inquisitive nature of children discussed in the opening paragraphs.

Physical Science — The molecular structure of Kevlar^® and its similarity to the molecular structure of nylon are important points of the reading.

Science and Technology — The reading explores aramids and the technology of high-strength fibers and flame-resistant materials.

History and Nature of Science — This biographical sketch clearly presents science as a human endeavor.
