Shang, Hao – Journal of Chemical Education, 2021
Here, we present an interdisciplinary educational project intended for high school chemistry that is focused on the establishment of a mathematical model to describe the relationship between conductivity and concentration, while linking chemistry to mathematics with the help of computer software. The project was designed to help high school…

Tofel-Grehl, Colby; Fields, Deborah – Science Teacher, 2015
Electronic textiles (e-textiles)--fabrics embedded with electrical or electronic components--offer a new model for teaching this content. E-textiles also engage students in programming and engineering design through nontraditional projects and materials. This article describes a four-week electricity curriculum using three e-textiles projects that…

Thomas, Nicholas C.; And Others – Journal of Chemical Education, 1989
Presents a laboratory experiment which illustrates the formation of tris(phenanthroline)cobalt complexes in the 2+ and 3+ oxidation states, the effect of coordination on reactions of the ligand, and the use of a ligand displacement reaction in recovering the transformed ligand. Uses IR, UV-VIS, conductivity, and NMR. (MVL)

Ramondetta, June – Learning, 1994
Students can explore temperature and heat conductivity by examining materials that make good cups for hot cocoa. Using temperature probes from computer-based science packages, students can measure gradual change in the liquid's temperature, watch as data are plotted on the computer, and explain why they chose a specific material.
