Is PKA in Chemistry?

AAAS (American Chemistry Society) is a highly regarded chemistry society for professional chemists. The Society includes members of all disciplines, including those in chemical engineering, biological science, civil and environmental engineering, computer science, earth sciences, mathematics, physics, materials science, electrical and electronics engineering, life sciences, engineering sciences, materials processing, and mechanical engineering. In addition, the Society provides educational programs and encourages research, education, and collaboration among its members. The AAAS consists of scientific committees, including committees for Education, Research, Education, and Technology. Membership in these committees allows scientists to network with other professionals in their area of expertise. It also provides opportunities for a variety of activities, from lectures and symposia to open houses and conferences. Some committees are devoted to particular areas of chemistry, such as development, imaging, molecular and atomic spectroscopy, or environmental chemistry. The American Chemistry Society is one of many that offers a variety of Chemical Demos, demonstrations of chemistry done in the laboratory. These programs are intended to provide participants with hands-on experience of the different processes in chemistry, as well as providing an opportunity to interact with other participants. What is PKA in Chemistry? AAAS offers three levels of PKA: Level I: One-on-one time in a small group, usually a few students and one faculty member, usually a professor. Lectures are conducted in a casual atmosphere. Level II: The process of molecular interaction in a larger group of students and scientists. Members of the group interact with a variety of chemistry demonstrations. Level III: A more formalized interaction between students and professors in a lab setting. This is typically taught by a faculty member who has years of experience teaching in labs. It is not necessary to complete Level III of PKA to take the other levels, but some people choose to do so in order to get a better feel for a particular method of demonstration. Students often work with a specific technique on one level, then move on to another in order to understand more. There are several formats for PKA. Each format contains several “presentations” for various sets of chemicals, and will end with a Q session for members to ask questions. In most cases, the presentations are arranged by various levels of chemistry, from basic to advanced. There are two ways to participate in a presentation: as a student or as a participant. Participating in a presentation means taking part in the chemistry demos. As a participant, participants are expected to answer questions about what they have seen, and to act as a guide for other participants. Some examples of PKA in Chemistry Demos include: protein structure, ion mobility, molecular mobility, colloidal suspensions, solid solutions, reaction products, nonlinear reactions, electron transfer, enantioselective adsorption, molecular transport, photo-oxidation, organic solvent exchange, reactions involving ligands, phenols, and compounds that are lipid soluble. Participants learn how to use chemistry demos as tools for understanding the scientific principles involved in chemistry. They also develop the skills required to make certain observations, describe what they see, and interpret their findings. AAAS offers additional examples of PKA in Chemistry Demos. Examples include: analogs and analogues, high-temperature experiments, biological sample analysis, biomass, inorganic and organic chemistry, and semisynthetic compounds. A list of available demos can be found online at the American Chemistry Society website.
