Rowe, Laura; Kubalewski, Maria; Clark, Robert; Statza, Emily; Goyne, Thomas; Leach, Katie; Peller, Julie – Journal of Chemical Education, 2019
Environmental pollution is both a worldwide and a local issue, and microplastic pollution in particular is receiving increased attention due to its prevalence and bioaccumulation potential affecting the food chain. This laboratory experiment uses current, research-based methods such that the students can determine the extent of microplastic…

Pino, Hernan; Pastor, Vanesa; Grimalt-Álvaro, Carme; López, Víctor – Journal of Chemical Education, 2019
In this article, a low-cost and pocket-sized setup for measuring CO[subscript 2] is presented. This setup is based on Arduinos, making it economic and open to modifications or improvements that satisfy other needs. It is composed of an Arduino board, a CO[subscript 2] sensor, an SD-card module, and a control panel. The device has been tested in…

Crandell, Olivia M.; Kouyoumdjian, Hovig; Underwood, Sonia M.; Cooper, Melanie M. – Journal of Chemical Education, 2019
The study presented here is a follow-up to a previous report in which we investigated how general-chemistry students in a transformed curriculum reason about simple acid-base reactions. In the present study, we use and adapt the previously developed coding scheme for a longitudinal study in which we follow students from general chemistry through…

Raff, Lionel M.; Cannon, William R. – Journal of Chemical Education, 2019
For 26 years, it has been assumed by some that the thermodynamics of open-system biochemical reactions must be executed by performing Legendre transformations on the terms involving the species whose concentrations are being held fixed. In contrast, standard nontransformed thermodynamics applies to chemical processes. However, it has recently been…

Schrader, Robert L.; Fedick, Patrick W.; Mehari, Tsdale F.; Cooks, R. Graham – Journal of Chemical Education, 2019
Typical laboratory exercises for undergraduate organic chemistry students involve bulk phase reactions with work up of product. In this study, students performed accelerated versions of the Katritzky reaction of para-substituted anilines with pyrylium salts in three ways: (i) by dropcasting reagents onto a paper surface and allowing solvent to…

Tan, Shun Yu; Hölttä-Otto, Katja; Anariba, Franklin – Journal of Chemical Education, 2019
A hands-on design activity named "electrochemistry designette" that incorporates design thinking with the aims to strengthen electrochemistry concepts, introduce prototyping ideas, encourage student class participation, and foster creativity is presented. This active learning activity, which lies at the interface of design and…

Gascon, Katherine N.; Weinstein, Steven J.; Antoniades, Michael G. – Journal of Chemical Education, 2019
The effect of surfactant adsorption on surface tension, as well as associated thermodynamic concepts are introduced in a laboratory experiment designed for undergraduate students. Using a reliable and accessible method, students measure the surface tension of aqueous solutions at different concentrations of sodium dodecyl sulfate. Students collect…

Croisant, Michael; Bretz, Stacey Lowery; Konkolewicz, Dominik – Journal of Chemical Education, 2019
The ACS Guidelines for bachelor's degrees in chemistry call for the curriculum to include polymer chemistry principles and the synthesis of different classes of macromolecules. Organic chemistry can provide an important introduction to polymer chemistry principles, and photochemically induced radical polymerization is one method for generating…

"Escape ClassRoom "CSI 1.0"" is an educational escape room proposed as an interactive analytical chemistry exercise for the evaluation of undergraduate students at the end of the subject. This approach is a new form of live action learning activity in which the students have to solve an analytical problem, namely, "an…

In recent decades, technology has become a constant presence in the chemistry classroom with online homework extensively used in many programs. Although research has pointed to both increased course performance and better study habits in classes that utilize online homework, little work has explored the extraneous load that these platforms place…

D'eon, Jessica C.; Faust, Jennifer A.; Browning, C. Scott; Quinlan, Kristine B. – Journal of Chemical Education, 2019
A safe and inexpensive laboratory for a first-year general chemistry course has been developed which allows students to explore important properties of carbon dioxide, particularly its behavior as a greenhouse gas. Students witness and measure air displacement to compare calculated gas densities and pressures inside a CO[subscript 2]-filled…

Costa, Samuel C.; Fernandes, Julio C. B. – Journal of Chemical Education, 2019
We developed a simple device to teach the concept of pH to visually impaired people through an experimental approach. An interface between a glass electrode and an open-source electronics platform based on easy-to-use hardware and software (Arduino Uno) was designed using an operational amplifier of ultralow input current. A headphone connected to…

Suroviec, Alice H.; Jones, Katarina; Sarabia, Grace – Journal of Chemical Education, 2019
Flavonoids have been studied extensively for their antioxidant properties. Specifically, the flavonoids in tea, such as catechin and epigallocatechin gallate, have been shown to have positive health effects. These compounds are also oxidizable, so the concentrations of these compounds in a given kind of tea can be determined using cyclic…

Wiggins, Marcie B.; Heath, Emma; Alcántara-García, Jocelyn – Journal of Chemical Education, 2019
The interface of art and science provides a broad range of educational and collaborative projects at various learning stages. Therefore, the use of historic artists' materials for teaching chemistry is receiving more attention. We prepared and used copper acetate (verdigris pigment) for a series of interconnected, lab-based activities, which can…
