Ediriweera, Meran Keshawa; Fernando, Dilusha; Thoradeniya, Tharanga; Warawitagei, Dilanthi Hewa; Siridewa, Kithmini – Biochemistry and Molecular Biology Education, 2023
The COVID-19 pandemic caused several educational challenges. Conducting laboratory experiments was an uphill task during the pandemic. Here, we developed a low-cost and reliable home-based experimental setup to teach column and thin layer chromatography (TLC) using silica gel granules available at home. Powdered silica gel, prepared by grinding…

Blagotinšek, Ana Gostincar – Physics Teacher, 2023
Two misconceptions about the mechanism of image formation in the human eye are common among students and even in textbooks and other teaching materials. The first attributes all refraction to the eye lens; the second treats the eye as a pinhole camera. To reduce these persistent conceptions of students, a series of simple experiments is presented…

Griselda L. Sosa; Guido E. Deluchi; Silvana A. Rami´rez; Mariana Hamer – Journal of Chemical Education, 2023
Understanding potentiometry is a difficult task when students in initial courses of Analytical Chemistry are first introduced to instrumental techniques. The closest instrument to them is a pH meter, which is frequently used as a "black box", without a real understanding of how it works. Here we present the assembly of jelly modules that…

Hal Van Ryswyk; Hanna Z. Porter; Connor K. M. Seto; Ixchel Lopez; Emma Dy – Journal of Chemical Education, 2023
Pulsed field gradient nuclear magnetic resonance (NMR) is used to estimate the size of quantum dots (QDs) produced in a simple, fast, small-scale synthesis. This upper-division laboratory experiment teaches the basics of QD synthesis and pulsed field gradient NMR, a powerful technique for measuring diffusion coefficients in solution. The diffusion…

John G. D'Angelo – Journal of Chemical Education, 2023
In recent years, course-based undergraduate research experiences (CUREs) have been increasing in popularity as replacements for or adjuvants to the traditional laboratory experience. This approach shifts the focus from an exercise-based curriculum to an experiment-based curriculum and provides students with a more authentic and higher-impact…
