Direct linkde Graaf, Ruvan; Crough, Kiernan; Steiner, Isaac; Hudson, Reuben – Journal of Chemical Education, 2022
A culinary exploration of the role of CO[subscript 2] in leavening is described. This demonstration substitutes dry ice for chemical leaveners in order to achieve the same pancake fluffiness. Under the universal framework of food and cooking, we developed this activity to bring aspects of phase transitions and chemical transformations to a broad…

Naibert, Nicole; Vaughan, Elizabeth B.; Brevick, Kylee; Barbera, Jack – Journal of Chemical Education, 2022
Although active learning strategies are being incorporated into many higher-education STEM courses, not all students benefit from these activities to the same extent. As these types of activities are designed to engage students in their learning, differences in student engagement may explain some of the differences in learning outcomes. However,…

Cionti, Carolina; Stucchi, Marta; Meroni, Daniela – Journal of Chemical Education, 2022
We here propose a simple and fast hands-on activity requiring limited equipment, to introduce students of various levels (bachelor's or high school) and backgrounds (from science to arts) to the chemistry of color. The different colors of stained glass are replicated through the deposition, on ordinary glass slides, of silica coatings colored by…

Chia, Vanessa Y. Y.; Ho¨ltta¨-Otto, Katja; Anariba, Franklin – Journal of Chemical Education, 2022
We provide an update on the "electrochemistry designette" in relation to its pedagogical effectiveness to students and experiential learning. We have previously proposed that the designette be applied as an assessment tool to measure the students' competence on electrochemical principles through a series of objective metrics. Based on…

Pasquarella, Kaitlyn; Jardine, Kayla; Hill, Kelly; Jones, Emma; Elia, Ralph; Gibbs, Greglynn; Sonntag, Matthew; Tribe, Lorena – Journal of Chemical Education, 2022
Computational chemistry techniques are used along with spectroscopy to characterize acetaminophen synthesized in an undergraduate chemistry laboratory experiment. The inclusion of electronic structure calculations to provide infrared and Raman spectra in the synthesis and characterization of acetaminophen connects over-the-counter medications with…

Kantor, Andrew G.; Scherr, Thomas Foster; Wright, David W.; Verberne-Sutton, Susan Denise – Journal of Chemical Education, 2022
Lateral flow assays (LFAs) have been used extensively for diagnosis of various diseases and conditions because they are inexpensive, rapid, robust, and easy to use. Incorporating LFAs into undergraduate chemistry courses could enrich the curricula by providing the students with a real-world application of analytical chemistry concepts,…

Schmuck, Viktoria D. E.; Romine, Isabelle C.; Sisley, Tyler A.; Immoos, Chad E.; Scott, Gregory E.; Zigler, David F.; Martinez, Andres W. – Journal of Chemical Education, 2022
An inexpensive at-home quantitative analysis activity was developed for the determination of glucose in unknown samples using paper-based microfluidic devices. All of the materials and reagents for the activity fit in a small kit that was mailed to students. The only items students needed to supply were water and a smartphone. Microgram quantities…

Lu, Alexander; Dong, Vy M. – Journal of Chemical Education, 2022
We present two simple classroom exercises designed to explain challenging concepts in conformation for students beginning organic chemistry. These macroscopic demonstrations serve as analogies to bridge students' understanding of flat two-dimensional drawings to real three-dimensional molecules. In the first demonstration, an apple is drawn from…

Cortés-Figueroa, José E. – Journal of Chemical Education, 2022
This communication describes an activity where upper-level chemistry students explore the determinability of rate constant values without concentration dependences (k[subscript true]) related to a solvent-ligand exchange in a transition metal carbonyl complex. By performing a series of multivariable linear regression (MVLR) analyses of…

Adams, William; Sonntag, Matthew D. – Journal of Chemical Education, 2022
Electrophilic aromatic substitution (EAS) represents an important class of reactions taught in the undergraduate organic chemistry curriculum. The EAS reaction of benzene and its substituted derivatives is generally described as proceeding through a carbocation (arenium cation) intermediate, and the regiochemistry of the product is heavily…

Jurinovich, Sandro; Domenici, Valentina – Journal of Chemical Education, 2022
UV-vis absorption spectroscopy is one of the most accessible spectroscopic techniques at the high school educational level, and it is usually introduced in analytical chemistry courses due to its high versatility and to the wide range of applications in many fields of chemistry. Within this framework, we have developed an easy-to-use"…

Clark, Ted M.; Dickson-Karn, Nicole M.; Anderson, Ellie – Journal of Chemical Education, 2022
Student performance calculating the pH of a strong acid or strong base solution before and after instruction in general and analytical chemistry courses was investigated using open-response questions in which a pH equation was not provided. Prior to instruction, students in both classes scored very low. General chemistry students lacking prior…

An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases "initiative's" Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent for biological…

Almeida, Karen H. – Journal of Chemical Education, 2022
US colleges and universities have known for decades that higher percentages of racial and ethnic subgroups leave STEM majors, contributing to racial inequality in STEM professions. Many interventions have been developed, yet the disparity persists. A partial flipped pedagogical model is presented for a General Chemistry 1 (GChem1) course that is…

Yu, Anne; Linden, Lilly E. – Journal of Chemical Education, 2022
A two-week exercise on the Flint, MI water crisis was developed for high school and undergraduate students in introductory chemistry courses. During the first week of the exercise, students learn the chemistry of lead contamination while reviewing concepts learned previously in the course. During the second week, the students participate in…
