Green, Michael; Chen, Xiaobo – Journal of Chemical Education, 2020
For undergraduate students to be prepared for graduate school and industry, it is imperative that they understand how to merge the theoretical insights gleaned through their undergraduate education with the raw data sets acquired through materials analysis. Thus, the ability to implement data analysis is a vital skill that students should develop.…

Babincáková, Mária – Journal of Chemical Education, 2020
Knowing the volume of evolved gases is helpful to select an optimal leavening agent for a particular application. The comparison of leavening agents, their reactions through the baking process in the modern and attractive way, is presented here. A gas pressure sensor probe was used to monitor the pressure change due to the carbon dioxide produced…

Bracker, Rachel; Dominguez, Kimberly; Stender, Anthony S. – Journal of Chemical Education, 2020
Nanoparticles are an increasingly important tool in chemistry research, but currently there are few opportunities for chemistry students to work with nanoparticles in undergraduate analytical courses. In this exercise, designed for an analytical or instrumental analysis lab course, students have the opportunity to work with solutions of silver…

Hancock, Laura M.; Hollamby, Martin J. – Journal of Chemical Education, 2020
Laboratory education is a defining feature of chemistry degree courses, with one of the fundamental aims being acquiring competency in a range of chemistry-specific practical skills, yet there are still limited reports of direct assessment of these skills. Here, we present the development, implementation, and evaluation of a station-based…

Ramesh, Vinay Bapu; Selvam, Athavan Alias Anand; Kulkarni, Surabhi; Manganahalli, Anusha Dattatreya; Bettadapur, Kiran R. – Journal of Chemical Education, 2020
High school students find reaction stoichiometry and the concept of the mole hard to comprehend. Teachers are well aware of the importance of teaching the mole concept and also the difficulty associated with it. In an attempt to improve the understanding of the mole concept with reduced difficulty, an atomic model kit that provides a hands-on…

Vyhnal, Christopher R.; Mahoney, Elizabeth H. R.; Lin, Yuan; Radpour, Roxanne; Wadsworth, Henry – Journal of Chemical Education, 2020
We present herein a module of pigment synthesis experiments that could be adapted and implemented in a variety of curricular settings. At the conclusion of each of the past two spring terms at our high school, we offered a 4 day short course on the chemical synthesis of pigments used in art. As part of the course, our students synthesized four…

La Frano, Michael R.; Amin, Samir; Fanter, Rob K. – Journal of Chemical Education, 2020
Metabolomics, the large-scale study of metabolites in biological fluids and tissues, offers the ability to observe metabolic changes in a broad context. Traditionally, nutritional metabolism education has focused on theory using textbooks. The objective of this study was to assess the effectiveness of involving students in a feeding research study…

Kornfeld, Jeannie; Stokoe, Scott – Journal of Chemical Education, 2019
Chemistry education has an important role in creating a sustainable path forward for humanity. By connecting chemistry education to a fuller understanding of the world, citizens and scientists will be more effective in addressing the coming complex challenges. This article presents a new approach to introducing high school chemistry that links to…

Mammino, Liliana – Journal of Chemical Education, 2019
Systems thinking is currently envisaged as a useful educational approach to teaching about sustainability (including green chemistry education) because of the high number of interrelated factors involved and the need of learners to acquire the ability to identify all of the factors and their relationships. After recalling the way in which key…

Stephens, Lisa I.; Mauzeroll, Janine – Journal of Chemical Education, 2019
One of the unique advantages of electrochemistry is that the relationship between thermodynamics and kinetics is quantitative, which is the basis of voltammetry. Mathematical models of electrochemical systems take advantage of this relationship to predict the effect of changing a system property (e.g., concentration, scan rate, or rate constant)…

Domenico, Janna; Schneider, Alexis M.; Sohlberg, Karl – Journal of Chemical Education, 2019
In this work, two exercises are described that are designed to teach students about the evolution and behavior of the electronic bands of graphene and bilayer graphene. These exercises involve performing extended Hückel molecular orbital theory calculations on polyacenes and polycyclic aromatic hydrocarbons. In the first exercise, students…

Cooper, Melanie M.; Stowe, Ryan L.; Crandell, Olivia M.; Klymkowsky, Michael W. – Journal of Chemical Education, 2019
The fundamental structure of a typical mainstream two-semester organic chemistry course, populated mostly by life science majors and taught at universities throughout the United States, has changed little since the 1970s. However, much of the research on learning in organic chemistry has been devoted to characterizing student difficulties of…

Katselas, Anthony; Motion, Alice; O'Reilly, Chiara; Neto, Chiara – Journal of Chemical Education, 2019
An experiment which investigates the wettability of natural surfaces was developed for undergraduate students, which allows them to explore concepts of surface structure, wettability, superhydrophobic surfaces, and self-cleaning. The students choose their own samples of leaves and flowers present in their local environment, examine their surface…

Johnson, Josiah W.; Mitchell, Christian D.; Deloach, Anna M.; Simpson, Hannah E.; Dunlap, Tori B. – Journal of Chemical Education, 2019
Protein structure, function, and signaling are a large portion of biochemistry. Because of this, proteins are often used as model systems in biochemistry laboratory courses, where a course-long project might comprise protein expression, purification, and characterization. Two common protein expression methods are isopropyl…
