An interdisciplinary and engaging practical is detailed which offers great versatility in the study of a qualitative and quantitative metabolism of azo-dyes by "Staphylococcus aureus". This practical has broad scope for adaptation in the number and depth of variables to allow a focused practical experiment or small research project. Azo-dyes are…

These proceedings contain the papers of the 18th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2021), held virtually, due to an exceptional situation caused by the COVID-19 pandemic, from October 13-15, 2021, and organized by the International Association for Development of the Information Society…

Describes an assay to determine the rate of photoreduction of 2,6-dichlorophenolindophenol (DCPIP). Acquaints students with experimental design and teaches them how to evaluate and communicate their results with the goal of enhancing their scientific literacy by integrating basic chemistry and arithmetic into their practical experience. (JRH)

Describes an interdisciplinary student experiment based upon the radiation effects on polymers, integrating some of the fundamentals of radiation chemistry, polymer chemistry, and material science. Also demonstrates how the information gained in the experiment has direct commercial application in product manufacture or processing. (CS)

Describes concrete laboratory manipulations in which time and its measurement are studied while investigating the parameters affecting the functioning of a pendulum. Also describes the origin of pendula and how cultural and historical references are integrated into laboratory practice. (Author/JN)

Develops a simple tree-ring laboratory to demonstrate the basics of dendrochronology. Provides two upper-level laboratory exercises primarily intended to demonstrate the specific dendrochronology subdisciplines of dendroclimatology and dendroecology. Suggests using the exercises separately or in unison as part of a multidisciplinary capstone…

Discusses how laboratory skills or experiences learned in a chemistry course can be used to help students to better understand physics. (ZWH)

Describes a laboratory activity which can be done with equipment normally available for introductory college courses. It measures the ratio of the radioactivity per unit mass of a unicellular alga to the radioactivity per unit mass of the medium in which it grows. (HM)

Uses a university campus as the focus for a study of the entire watershed. Presents a context for incorporating pedagogical elements, interdisciplinary teaching, research experience, and active, collaborative strategies into a useful framework for undergraduate science education. (Author/KHR)

Describes an interdisciplinary chemistry course at the New Jersey Institute of Technology (NJIT) in which at least one quarter of the time is devoted to materials science. Includes information on course content, laboratory work, and assessment of student performance on chemistry and materials science topics. (JN)

Describes a multidisciplinary project/experiment in which undergraduate students repaired a nonfunctional Helium-Neon laser. Includes experimental procedures used and results. (JN)

Presents a protocol that gives students hands-on experience in generating a meaningful physical map of a circular molecule of DNA. Topics include agarose gel electrophoresis, logic of restriction maps, extracting data from an agarose gel, managing data from gels, experimental protocol, loading gels, electrophoresis, photographing gels, collecting…

This paper presents the experiment being conducted in the Electric Circuits II course (ELE1103) at PUC-Rio's Electrical Engineering Department since March 1997. This experiment was held in both the fall and the spring semesters of 1997. The basis for the experiment was concurrent teaching methodology, to which the principles of entrepreneurship…

This paper describes the author's experience of designing and teaching an interdisciplinary course titled "Light", in collaboration with a visual artist. The goals of the course, texts used, laboratory work, art studio work, and other course activities are discussed with an emphasis on how light was used as a theme to make connections between…

Describes a series of experiments monitoring household energy use and expense being developed as part of a course in an adult education program at Wayne State University. The experiments are used in a one-semester workshop course in which resources, consumption patterns, and future outlook are discussed. (Author/SK)
