Lipton, Mark A. – Journal of Chemical Education, 2020
The material of a standard second-year undergraduate organic chemistry class has been reorganized and reframed to emphasize the mechanistic connections between reactions and to clarify the language with which organic reaction mechanisms are discussed. Assessment of the results of this reorganization shows that student test scores do not decline in…

Barnett, Kerry L.; Shea, Kevin M.; McGeough, Catherine; Trotta, Kristine; Williams, Steven; Ly, Minh; Aloisio, Kathryn – Journal of Chemical Education, 2020
A semester-long research project for second-semester organic chemistry lab sections was developed. Student projects were based on preliminary data from faculty research that suggested the natural product neurolenin B to be a treatment for lymphatic filariasis. Students isolated neurolenins from the Central American plant "Neurolaena…

Crisler, Glenn B., II.; Perera, Viveka; Hernandez, Cintly Guzman; Orr, Andre; Davis, Roger; Moore, Jessie; Smith, James; Varco, Jac; Schauwecker, Tim; Brown, Ashli; Mlsna, Todd; Mlsna, Deb – Journal of Chemical Education, 2020
This paper presents an experimental lab designed for undergraduate students which focuses on soil science and chemistry. Students perform a series of tests to classify soil's phosphate retaining characteristics, texture, pH, organic matter content, and permeability with the addition of a novel soil amendment, Al Mg biochar. This lab has minimal…

Xie, Mingrou; Inguva, Pavan; Chen, Wenqian; Prasetya, Nicholaus; Macey, Andrew; DiMaggio, Peter; Shah, Umang; Brechtelsbauer, Clemens – Journal of Chemical Education, 2020
The objective of the presented module is to train students with no background in process development and scaleup of chromatographic processes to a high level of competency within 40 contact hours. The key pedagogical approach is "progression" where students' capabilities are gradually built up with appropriate scaffolding provided at…

Panda, Debashis; Patra, Soumyadip; Awasthi, Mahendra Kumar; Singh, Sanjay Kumar – Journal of Chemical Education, 2020
To understand critical problems associated with solid waste and its consequences for the environment, a laboratory experiment is presented on the synthesis of aluminum-based metal-organic framework (MOF) MIL-53(Al) from household waste (PET bottles and aluminum foil/can), for undergraduate students of chemistry. This work is designed to teach…

Higgins, Pamela J. – Journal of Chemical Education, 2020
Most forensic chemistry experiments focus on the usual suspects involving criminal scenarios: illicit drug identification, gunshot residue detection, blood and fingerprint analysis, and arson investigations. However, environmental forensics involves chemical techniques that can expand the breadth of experience for forensic chemistry students. An…

Fazal, Md. Abul; Raigoza, Annette F.; Strollo, Christen M.; Peterson, Alicia A. – Journal of Chemical Education, 2020
Fundamentals of Macroscopic Chemical Analysis is a newly developed foundation-level course that integrates concepts from traditional physical and analytical chemistry courses. The course was designed to serve majors in chemistry, biochemistry, and biology as well as pre-health professional students. The main goal of this course is to develop the…

Sjo¨stro¨m, Jesper; Eilks, Ingo; Talanquer, Vicente – Journal of Chemical Education, 2020
The decisions and actions that chemistry educators make regarding why, what, how, and when to teach certain content or implement a specific instructional activity are often guided, but also constrained, by explicit or implicit "didaktik models". These types of models direct our attention and actions when designing curricula, planning for…

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…

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…

Morales-Vidales, J. Abraham; Salazar, S. Alejandro Sandoval; Jacobo-Fernández, Jimena M.; Tlahuice-Flores, Alfredo – Journal of Chemical Education, 2020
This work covers a three-week program designed to provide undergraduate students with a background in structural chemistry and materials science. Sessions are based on the programming of regular polyhedra and their geometrical relationships by using an object-oriented language (i.e., POV-Ray). Three lectures introduce the basics of programming…

Young, Charles G.; Volaric, Sioe See – Journal of Chemical Education, 2020
This paper describes an upper-division undergraduate exercise involving the synthesis and iodometric and infrared spectroscopic analysis of the peroxide double salt [Zn(NH[subscript 3])[subscript 4]][Mo(O[subscript 2])[subscript 4]]. Here, iodometric methods are employed to determine the peroxide content of the compound, a procedure widely used…

Kerdkaew, Thitipong; Limpanuparb, Taweetham – Journal of Chemical Education, 2020
To prove that oxygen is irreversibly consumed in the blue bottle reaction, a manometer or a plastic bottle was used to show a permanent reduction in the gas pressure in a reaction vessel. This demonstration may be misleading because the change in gas pressure can be attributed to a number of other factors such as temperature change and involvement…

Xue, Dihua; Stains, Marilyne – Journal of Chemical Education, 2020
Understanding resonance is essential to predict chemical reactivity and explain reaction mechanisms. Despite its importance in the organic curriculum, few studies have explored students' difficulties with this concept and faculty's instructional approaches to teaching it. The goals of this study are to address this gap in the literature by (1)…
