A novel teaching approach is aimed at elucidating the concept of bond enthalpy for general chemistry students. Through the integration of a hands-on candy pulling activity, students in a large lecture class were provided a tangible experience to explore bond strengths using rope candy and a luggage scale. Feedback from students indicated a clear…

Mo´nica I. Garci´a-Aranda; Marco Franco-Pe´rez; Angel Zamudio-Medina – Journal of Chemical Education, 2023
Heterocyclic compounds are an integral part of research, particularly in the pharmaceutical field. The synthesis of such compounds in an undergraduate laboratory can help students understand the relevance and importance of their field of study. Our experimental activity introduces a novel procedure to synthesize coumarin, a heterocyclic formed by…

Jessica K. Kisunzu – Journal of Chemical Education, 2023
Discussions of the primary literature are an important part of undergraduate education, and much work has been done to develop methods of integrating the literature into the curriculum. Examples include individual single-article discussion activities, literature-based courses, and regular journal club events. While many published examples focus on…

Siddiqui, Khawar S.; Poljak, Anne; Ertan, Haluk; Bridge, Wallace – Biochemistry and Molecular Biology Education, 2022
Determination of enzyme activity is crucial for discovery, research, and development in life sciences. The activity of enzymes is routinely determined using spectrophotometric assays that measure rates of substrate consumption or product formation. Though colorimetric-based detection systems are simple, rapid, and economical to perform, the…

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…

Samuelsson, Christopher Robin; Ho, Felix M.; Elmgren, Maja; Haglund, Jesper – Chemistry Education Research and Practice, 2023
This study adds to the growing body of research on laboratory work. The study involves four pairs of students in a university introductory calorimetry lab of which two pairs, the IR-pairs (infrared camerapairs), were given access to infrared cameras to use however they liked during their course lab work. Two other pairs, the T-pairs…

Keen, Clarissa; Sevian, Hannah – Chemistry Education Research and Practice, 2022
Learning and learning goals in undergraduate chemistry laboratory have been a popular research topic for the past three decades due to calls for curriculum reform, cost justification, and overall efficacy of necessary skill development. While much work has been done to assess curricular interventions on students' learning and attitudes towards…

Trivedi, Vishwa D. – Biochemistry and Molecular Biology Education, 2022
Protein structure-function relationship serves as the primary learning outcome in any undergraduate biochemistry course. We expanded the protein structure-function exploration, PSFE initiative during COVID-19 to provide more effective and engaging experience to our undergraduates in biochemistry and independent research courses. Multiple…

Dauzvardis, Fabian; Lisensky, George – Journal of Chemical Education, 2021
Ion-selective electrodes are among the oldest and most important potentiometric sensing methods. In this experiment, students assemble their own reusable ion-selective electrode from glass tubes with an attached PTFE membrane, [(CH[subscript 3]CH[subscript 2]CH[subscript 2]CH[subscript 2]CH[subscript 2]CH[subscript 2]CH[subscript 2]CH[subscript…

Lincoln, James; Barrueto-Cabello, Roberto – Physics Teacher, 2021
X-rays are such an important and familiar part of the electromagnetic spectrum, but is there a way to safely bring x-rays into your lecture? The demo team at the University of California at Berkeley seems to have managed this. They have an x-ray safe box that they use to produce a live x-ray image on a fluorescent screen. In this article, we…

Keira D. Naff; Jeri L. Tyler; Dima H. Hamza; Jonathan D. White – Journal of Chemical Education, 2023
Structure--activity relationships are foundational concepts in biochemistry and drug design. Despite their importance, it can be difficult to create and execute laboratory activities that allow students to directly observe the interactions between small-molecule drugs and their biomolecular targets. Here, we report an activity that investigates…

Romero-Abad, David; Reyes-Portales, José-Pedro – Physics Education, 2021
During their first physics courses, most students struggle with mathematical concepts that are used but not fully understood, for example, the appearance of infinity in introductory physics exercises. In many cases, these concepts are critical to understanding the underlying physical phenomenon. Typically, most books do not place much emphasis on…

A laboratory exercise for undergraduate advanced students of enzymology and biocatalysis is presented. Since enzyme assays can be quenched or continuous, this experiment compares the performance of two quenching agents for lactase, in a continuous setup. Enzymatic activity of [beta]-galactosidase ("Aspergillus oryzae") was determined…
