This paper outlines a comprehensive teaching laboratory course program that centers on titration analysis, a timeless and essential technique in analytical chemistry spanning various disciplines, such as environmental science, medicine, and industry. In these fields, titration analysis is paramount for determining the concentrations of substances…

Background: The adoption of virtual laboratories (VLs) has experienced a significant surge, catalysed by the global changes in the educational landscape, notably influenced by the COVID-19 pandemic. Originally supplementary to traditional in-person laboratory experiments, VLs swiftly transitioned into a primary source of hands-on laboratory…

Performing HPLC-based experiments in the undergraduate practical classroom is difficult because of the time required to perform an analysis. This limits the type of practical to one that undertakes a simple quantitative analysis. However, with the use of sophisticated simulators, such as the one employed in this exercise, more complex experiments…

A virtual catalytic reactor laboratory (VCRL) experiment, which can be used in most browsers, is described. Students select feed conditions and use the VCRL to take data for a gas-phase catalytic reaction and fit kinetic parameters to a Langmuir-Hinshelwood rate expression. The VCRL contains instructions, equipment descriptions, an animated…

Fluency in both the construction and interpretation of molecular structures is a critical learning objective in the second-year organic chemistry curriculum. With the introduction of PerkinElmer's ChemDraw structure drawing tool into undergraduate laboratory courses, students are challenged to develop fundamental molecular drawing skills using…

Explanation of natural phenomena at one level of biological organisation almost always involves causes that are found at other levels. Although scientists thinking across levels find it easy to explain physiological phenomena, students often perceive this as a challenge. We developed a new graphic organiser called Zoom Map, which is a mode for…

The analysis of spontaneous tail coiling (STC) in zebrafish embryos is a functional parameter that allows the study of motor development. It has recently gained relevance as a biomarker to assess the neurotoxicity of environmental substances. Its practicability in the laboratory makes it an excellent pedagogical tool for promoting students'…

The understanding of the basic principles of chromatography is of high importance for chemistry, pharmacy, and biology students. In this paper, we present a free web application which can be used as a teaching tool to introduce chromatography to undergraduate students, using one of the simplest chromatography models: the plate theory.

CRISPR-Cas9 is revolutionizing how we conduct scientific research, treat disease, and develop new crops. The widespread impact of this genome-editing technology makes it critical for undergraduate students to understand and engage with this new tool. In this article, we describe a multi-week lab module that teaches undergraduates how to design…

The Beer-Lambert law is a fundamental relationship in chemistry that helps connect macroscopic experimental observations (i.e., the amount of light exiting a solution sample) to a symbolic model composed of system-level parameters (e.g., concentration values). Despite the wide use of the Beer-Lambert law in the undergraduate chemistry curriculum…

The rapid evolution of Artificial Intelligence (AI) is profoundly shaping our society. Among various AI tools, ChatGPT stands out for its user-friendly nature and wide accessibility to the public. However, despite their countless potential benefits, these tools also face significant challenges, especially in sensitive areas like Education. In this…

A series of Microsoft Excel spreadsheets were developed to simulate the process of separation optimization under isocratic and simple gradient conditions. The optimization procedure is performed in a stepwise fashion using simple macros for an automatic application of this approach. The proposed optimization approach involves modeling of the peak…

This study explored, using a qualitative research design, the experiences of chemistry laboratory staff and students engaged in chemistry laboratory exercises delivered online. The research was completed over two semesters for the academic year 2020-2021 at The University of the West Indies, St. Augustine Campus in Trinidad and Tobago. The group…

A series of computer-based laboratory experiments have been developed to aid undergraduate students in appreciating the three-dimensional nature of chemistry and biochemistry. Both lower- and upper-division experiments have been developed. Students are introduced to the use of ChemDraw for the production of professional-quality molecular…

General safety and chemical training of undergraduate students is typically held at the first-year level. In this technology report, we propose a flexible strategy to improve students' general knowledge of safety for a second-year inorganic chemistry laboratory. The strategy is composed of an online interactive revision approach through the…
