A Maker-oriented experimental course in general chemistry has been created by using digital tools, such as a computer, a pressure sensor, and data processing software, in combination with a new multiple expansion method and laboratory equipment to determine the vapor pressure precisely. In this Maker chemistry experiment, the pressure sensor…

This report offers technical guidance and encouragement for any instructor or department looking to produce valuable, high-quality Lightboard teaching videos under space and budget constraints. Lightboards were introduced in a chemical education setting around 2015 as a presentation setup that allowed the presenter to speak face-to-face to their…

Given the growing prevalence of computational methods in chemistry, it is essential that undergraduate curricula introduce students to these approaches. One such area is the application of machine learning (ML) techniques to chemistry. Here we describe a new activity that applies ML regression analysis to the common physical chemistry laboratory…

Chemistry education research demonstrates the value of open-ended writing tasks, such as writing-to-learn (WTL) assignments, for supporting students' learning with topics including reasoning about reaction mechanisms. The emergence of generative artificial intelligence (AI)technology, such as chatbots ChatGPT and Bard, raises concerns regarding…

In case-based learning, students develop and apply course knowledge to solve tangible and "real life" problems. This practice can enhance student motivation and engagement in the analytical laboratory. In this application of case-based learning students analyze commercially available oils for CBD content. In the state of Texas anyone can…

In this guided inquiry experiment, students extract catecholase enzyme from apples to catalyze the oxidation of catechol. They follow the reaction using the UV--vis absorbance of the "p"-benzophenone produced to determine the Michaelis-Menten kinetic parameters. Students make selected experimental choices within a structured framework…

Minimizing the energy consumption of desalination processes is an important goal for augmenting freshwater production and mitigating water scarcity. Chemical, civil, mechanical, and environmental engineering students can derive and analyze the energy consumption of desalination processes by applying engineering fundamentals such as thermodynamics,…

Photochemical synthesis, in which light is used as an indispensable reagent, is recognized as a green technique for organic synthesis and has been paid extensive attention. In this laboratory experiment for chemistry classes, a photoinduced C-C coupling reaction is introduced, which can be conducted under mild conditions at room temperature.…

The study explores children's emerging understanding of an important science concept in chemistry. Play-based learning activities were designed for children to experience and imagine the concept of 'small' as used in chemistry, moving from the visually experienced level of 'small' towards more imaginative understandings. Data were collected…

Column chromatography of photosynthetic plant pigments is a common experiment in introductory laboratory courses for science majors and nonscience majors alike. We report a simple, rapid, reproducible, and small-scale solid--liquid extraction of photosynthetic pigments from inexpensive, store-bought dried herbs that affords a dark-green extract…

This current study explored twelfth-grade students' conceptions regarding electrochemistry in the Ximhungwe circuit of the Bohlabela district in the Mpumalanga province of South Africa. The sequential explanatory design was used to gather and analyse quantitative data first before gathering and analysing qualitative data for the current study. In…

This article describes a simple and inexpensive "shock and awe" classroom demonstration for understanding the importance of carbon dioxide (CO[subscript 2]) in acid-base regulation. Before class, a solution was prepared by adding sodium bicarbonate and universal indicator solution to a sample of distilled water contained in a standard…

Teaching pedagogical content knowledge (PCK) at a topic-specific level requires clarity on the content-specific nature of the components employed, as well as the specific features that bring about the desirable depth in teacher explanations. Such understanding is often hazy; yet, it influences the nature of teacher tasks and learning opportunities…

The redox reaction between dioxovanadium(V) and oxalate is proposed as a suitable system to analyze the kinetics of a twostep reaction mechanism using UV-vis spectroscopy. First, the spectra of dioxovanadium(V) and its reduced counterpart oxovanadium(IV) are compared and explained using the crystal field theory. The change in absorbance can be…

Different virtual chemistry laboratories (VCLs) have been developed with which students can perform and practice their practical and experimental work, thus increasing their learning before performing the same work in a real chemistry laboratory. In this paper, we present an analysis of the existing virtual chemistry laboratories by identifying…
