Ressia, Delfina; Ferro, Macarena A.; Trobiani Di Canto, Juliana A.; Saugo, Melisa; Ciolino, Andrés E. – Chemical Engineering Education, 2023
This paper reports the quantification of Ca, Mg, and Fe as micronutrients in different vegetables (spinach, sugar beets, and carrots) from raw and processed samples. Simple extraction procedures, titrations, and spectrophotometric analysis were used to determine the amounts of micronutrients before and after cooking. From the obtained results, an…

Saowarux Fuangswasdi; Wanlapa Aeungmaitrepirom; Vanida Nilsom; Pritsana Ralakhee; Pumidech Puthongkham – Journal of Chemical Education, 2023
The COVID-19 pandemic, which emerged in early 2020, forced educational institutions in Thailand to chiefly rely on online learning during the government mandated lockdown for almost two academic years. Although migration to the online format seems to suit lectures, it is inadequate for laboratory courses since students could not do the experiment…

Rafael F. A. Gomes; Carlos A. M. Afonso – Journal of Chemical Education, 2023
A laboratory experiment was developed for the continuous flow preparation of an aminal derived from the condensation of furfural with morpholine. The experiment introduces the students to concepts of green chemistry, heterogeneous catalysis, and continuous flow. A cheap and easy setup allows the heterogeneous catalyst reactor to be built in class.…

Pascal Kaneza; Jean Baptiste Nkurunziza; Innocent Twagilimana; Thumah Mapulanga; Anthony Bwalya – Cogent Education, 2024
This study aimed to examine the effect of three teaching approaches: The traditional teaching method, Teacher based demonstration experiment (TBDE), and the Student hands-on experiment (SHE), on students' conceptual understanding of solutions and titration. The data were collected using a chemistry achievement test (CAT) comprising of 30…

Elia Bergamin; Giacomo Fabris; Matteo Neffat; Paola Baron Toaldo; Daniela De Luchi; Renato Bonomi – Journal of Chemical Education, 2023
A class of 18 students attending the last year of an Italian high school was divided into groups and performed the extraction of pigments contained in hibiscus tea. Each group worked at a different temperature and carried out multiple extractions using distilled water as a solvent. By means of UV-vis spectroscopy it was possible to determine the…

Mitchener, Nick – Physics Education, 2020
A simple, cheap, and easy to make ionisation chamber to investigate the decay of Radon-220. Requires no expensive meters, experiment is carried out using thoriated gas mantles to produce the Radon-220, and the chambers are used with low cost digital multimeters. An opportunity for 16-18 students to carry out a hands-on experiment with an ionising…

Peter Gimby; Wesley Ernst; Christopher Cully; Ania Harlick – Papers on Postsecondary Learning and Teaching, 2024
The switch to online learning required a creative solution to allow for the experiential learning outcomes of the program to be satisfied when access to physical spaces and equipment was restricted. This paper describes a collaborative process between technical and support staff as well as research and teaching faculty that led to the creation of…

Zareen Amtul; Moutasem Seifi; Erfan S. Asif; Athar Ata – Journal of Chemical Education, 2023
According to national labor market information study, access to talent is the greatest business challenge Canadian biotech companies are facing. We, therefore, developed, implemented, and assessed a pharma industry-inspired, medicinal research laboratory module in an experiential capstone biotechnology laboratory course. This involves developing a…
