In recent years, pedagogical advancements have allowed the adoption of more engaging forms of course assignments to help students better understand and communicate chemistry. In this context, informational graphics, known as infographics, emerge as an effective teaching aid in educational settings and in disseminating scientific content to the…

pH determination and acid-base titrations are essential experiments performed by high school and university undergraduate students alike throughout their chemistry education. While these experiments often rely on conventional pH meters for quantification and pH test strips or indicators for qualitative assessments, we demonstrated herein that a…

Chemists have always designed and deployed cross-disciplinary approaches that interface chemistry with other disciplines to proffer solutions to many human problems. We designed a laboratory experiment that implements chemistry concepts in a biological model to prime undergraduate students to appreciate interdisciplinarity as an approach to…

This communication describes an updated experiment of peptide synthesis, involving determination of the loading capacity of a Fmoc-protected amino functionalized resin using UV-vis spectroscopy and a subsequent synthesis of a dipeptide in order to exemplify the experimental solid-phase synthesis procedure as an alternative technique in organic…

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…

Pharmaceutical Integrated Experiment (PIE) is a systematic and comprehensive compulsory course for undergraduates majoring in pharmacy and pharmaceutical engineering. This course mainly focuses on integrating the theoretical knowledge of various disciplines into practice, enabling students to master the key processes of drug research and…

Cycloadditions in combination with multicomponent reactions are among the most valuable synthetic tools used by organic chemists to construct cyclic and heterocyclic compounds in a straightforward way. Although cycloadditions, such as the Diels--Alder reaction, are mainly covered in basic and advanced organic courses for undergraduate students,…

Silver and its compounds have been widely used in experimental teaching, industrial production, and other fields. In these processes, a large amount of wastewater containing silver is usually produced, which might contribute to environmental pollution. Therefore, recycling silver from wastewater not only has good economic value but also meets the…

Apparatus catalogues of the first half of the 20th century contain a number of clever and simple devices for measuring the index of refraction of a liquid. In some cases students can put together one of these pieces of apparatus and then make their own measurements. The Gilley board was one of the devices that caught my eye, and I would like to…

Potassium tris(oxalato)ferrate(III) trihydrate is a commonly prepared coordination compound in general or upper-level chemistry laboratories and can be recycled to grow large single crystals that instructors may display when introducing the experiment to classes. Showing the crystal's shape can also be used to briefly introduce students to X-ray…

An easy circuit for measuring the power of a solar panel in physics classroom by using the microcontroller Arduino will be introduced in this article. The measured data is transferred via Bluetooth to the smartphone app 'phyphox' where it is displayed graphically. The circuitry enables measuring the power of a solar panel in different situations…

Optimization of experimental conditions in chromatography is recognized as a wear-and-tear process involving hundreds of experiments in order to maximize the number of separated compounds for each sample. The critical thinking skills and practices entailed cannot be achieved with students in a conventional lecture class. This report provides a…

The use of smartphones in experimental physics is by now widely accepted and documented. PASCO scientific's Smart Cart, in combination with student-owned smartphones and free apps, has opened a new universe of low-cost experiments that have traditionally required cumbersome and expensive equipment. In this paper, we demonstrate the simplicity,…

Friedel-Crafts alkylation reactions using a curated set of alcohols provide students with the opportunity to combine the study of electrophilic aromatic substitution with carbocation rearrangements. In this experiment students may be presented with up to nine alcohols that yield six products, all synthesized under identical reaction conditions.…

Although ripple tanks have been used in the past to perform wave simulations for electromagnetic and acoustic phenomena, especially before the advent of computers, they are still often used to demonstrate wave propagation in high school and college physics classrooms. Usually ripple tanks have a rectangular shape. The wave propagating through the…
