Nehring, Andreas; Busch, Sebastian – Journal of Chemical Education, 2020
Although demonstrations play a central role in teaching and learning chemistry, the effects of concrete setup principles have rarely been subject to systematic empirical studies. According to the left-to-right principle, the educator should begin with the first step of a reaction in the upper left part of the setup and then place the following…

Kodani, Satoki; Fukuda, Masahiro; Tsuboi, Yoji; Koga, Nobuyoshi – Journal of Chemical Education, 2020
This study focuses on designing a laboratory learning program for a high school chemistry course in which students could discover the fundamental principles of Hess's law via stepwise inquiry. By exploring the chemical properties of common desiccants, mainly those that were reactive in water, students were introduced to the exothermic reaction of…

Dauzvardis, Fabian; Knapp, Alexander; Shein, Kaung Nan Dar; Lisensky, George – Journal of Chemical Education, 2020
In this brief experiment, students create a superhydrophobic surface as an application of polar--nonpolar interactions and redox chemistry. Half of a zincgalvanized steel strip is coated in copper nanoparticles through electroless deposition. A layer of nonpolar octadecanethiol is added to half of that copper surface. Students classify the three…

Lai, Heyun; Li, Ziqi; Zhu, Shunying; Cai, Longfei; Xu, Chunxiu; Zhou, Qing – Journal of Chemical Education, 2020
This communication describes a method to detect aluminum in gastric drugs by the naked eye using a microfluidic paper-based analytical device ([mu]PAD). Aluminum ions react with chrome azurol S (CAS) and cetyltrimethylammonium bromide (CTAB) to form a colored complex, which generates a colored band on the [mu]PAD. A printed ruler can be used to…

Lam, Chun Ho; Jackson, James E. – Journal of Chemical Education, 2020
Electrocatalytic hydrogenation of acetol (IUPAC: 1-hydroxy-2-propanone), a species formed upon thermal liquefaction of biomass, can be achieved using inexpensive objects: filter paper, coins, batteries, salts, and water. This simple example demonstrates that "green" chemical transformations can be achieved with familiar items and helps…

Stepek, Iain A.; Hofmann, Raphael; Nichols, Paula L.; Aschwanden, Andrea; Eckard, Christophe; Aschwanden, Patrick; Bode, Jeffrey W. – Journal of Chemical Education, 2020
Despite the importance of organic chemistry to human health and quality of life, very few outreach programs have been successful in communicating this message. This contributes to negative public perceptions of organic chemistry and obscures the enormous advances in quality of life engendered by organic synthesis. New chemical outreach programs…

Azman, Adam M. – Journal of Chemical Education, 2020
Fast, reliable, well-resolved latent fingerprints can be planted by applying a thin coating of a 50:50 mixture of hand lotion and food-grade protein powder. Fingerprints can be revealed with iodine fuming or ninhydrin staining. This low-cost alternative to commercial latent print pads can be used in a variety of classroom or public settings where…

Hike, Nina; Hughes-Phelan, Sara J. – Journal of Chemical Education, 2020
To be literate in modern society no longer means that one can simply read and write. In our rapidly changing world where information is available with a few taps of our fingers, critical thinking and process-oriented learning have become an essential part of being literate. Therefore, when many of the states decided to create a unifying set of…

Nunes da Silva Júnior, José; Santos de Lima, Paulo Roberto; Sousa Lima, Mary Anne; Monteiro, Álvaro Carvalho; Silva de Sousa, Ulisses; Melo Leite Júnior, Antonio José; Vega, Kimberly Benedetti; Oliveira Alexandre, Francisco Serra; Jalles Monteiro, André – Journal of Chemical Education, 2020
This report provides information about a free-of-charge, trilingual (Portuguese, Spanish, and English) game-based application that engages high school and undergraduate students in reviewing the structural theory of organic compounds in a challenging way. In Time Bomb Game, students must disarm a time bomb on their own by correctly answering…

Ling, Yizhou; Chen, Pengwen; Li, Juan; Zhang, Junyao; Chen, Kai – Journal of Chemical Education, 2020
This paper proposes an experiment in which students build microdevices for conveniently electrolyzing water and use image recognition and processing technology to measure the volume of gas generated during the reaction in a noncontact way. Taking advantage of three ratio relationships between (i) gas volume and the area of bubbles, (ii) the…

Garrido, Neil; Pitto-Barry, Anaïs; Soldevila-Barreda, Joan J.; Lupan, Alexandru; Comerford Boyes, Louise; Martin, William H. C.; Barry, Nicolas P. E. – Journal of Chemical Education, 2020
The abstract nature of physical chemistry and spectroscopy makes the subject difficult to comprehend for many students. However, bridging arts and science has the potential to provide innovative learning methods and to facilitate the understanding of abstract concepts. Herein, we present a high-school project based on the conversion of selected…

Paiva, Victor T. C.; Parma, Eduardo; Buffon, Regina – Journal of Chemical Education, 2020
For the past 10 years, the Virtual Tournament of Chemistry, TVQ, has been held in Brazil, engaging high school students with challenging questions that require cooperation, effort, and a literature search, while exploring the advantages of the Internet as a tool for self-instruction. The tournament has worked both as a way of narrowing the gap…

Rodriguez-Vasquez, Kelly A.; Cole, Aaron M.; Yordanova, Desislava; Smith, Rachel; Kidwell, Nathanael M. – Journal of Chemical Education, 2020
To empower high school and undergraduate students to become citizen scientists, we describe the design, construction, and operation of a multisensor device based on Arduino microcontroller technology to record atmospheric measurements relevant to secondary organic aerosols (SOAs). The handheld "AIRduino" multisensor device was built and…

Wang, Xisen; Chrzanowski, Matthew; Liu, Yujuan – Journal of Chemical Education, 2020
A safe, convenient, and environmentally benign laboratory experiment for the synthesis of biodiesel from six kinds of vegetable oils has been developed for the introductory organic chemistry laboratory. The experiment uses ultrasonic irradiation in the presence of a base catalyst at room temperature and atmospheric pressure. Because of safer and…

A laboratory activity is described for senior high school or first year undergraduate level students that illustrates key concepts linked to extractive metallurgy. This experiment demonstrates preferential binding of a methoxyphenolic oxime ligand to Cu[superscript 2+] in the presence of other transition metal ions in aqueous solution. The…
