The continuous distillation experiment in the Unit Operations Lab was moved to a virtual platform. Students used old data and equipment specifications to simulate the column in Aspen HYSYS. Students experimented without the limitations of existing equipment. For example, they studied the number of trays in the virtual column, something that is…

Course-based undergraduate research experiences (CUREs) have emerged as a promising approach to enhance undergraduate STEM education by engaging students in authentic discovery. CUREs integrate genuine research projects into undergraduate courses, providing students with a real research experience while earning academic credit. While CUREs offer…

Virtual experiments are widely used in the field of education for their low cost, strong interaction, hyperspace and safety advantages. While some researchers have analysed the impact of virtual technologies such as AR or VR on teaching effectiveness, few researchers have comprehensively explored the impact of virtual experiments on students'…

A laboratory experiment that exposes students to fundamental concepts in kinetics and statistical thermodynamics to study systems of great current interest in nanotechnology by employing a foundational technique in physical chemistry is described. A modified commercial flash photolysis spectrometer was used to study photoinduced isomerization…

A laboratory experiment was developed for the continuous flow preparation of an aminal derived from the condensation of furfural with morpholine. The experiment introduces the students to concepts of green chemistry, heterogeneous catalysis, and continuous flow. A cheap and easy setup allows the heterogeneous catalyst reactor to be built in class.…

Knowledge related to photochemistry has been gradually introduced as a part of chemistry courses at both undergraduate and postgraduate levels. However, due to their complex conceptual principles, limited class time, and tedious experimental setup and methodologies, students tend to encounter difficulties in understanding the concepts and…

In an effort to further develop critical thinking and problem solving skills, a guided-inquiry-based, multioutcome organic chemistry synthesis and characterization experiment was developed. Students were provided with the protocol for a time-saving microwave-assisted acetanilide synthesis reaction from acetic anhydride and an unknown primary aryl…

Even though scientific communication and collaboration play critical roles in academic success, they often come in second to teaching laboratory fundamentals. COVID-19 associated capacity constraints forced our program to reexamine the traditional laboratory instruction paradigm by limiting physical attendance, as well as laboratory duration.…

Background/purpose: The current trend of training Chemistry teachers focuses on innovating pedagogical methods and developing students' holistic competencies, particularly their chemistry experimentation competencies (CEC). The CDIO (Conceive - Design - Implement - Operate) framework effectively combines theoretical knowledge with practice and…

The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

Amides are usually prepared using amines and acyl halides, which often implies a two-step procedure. Alternatively, coupling reagents can be used in a single-step reaction with good yields, which seems to be suitable for organic chemistry laboratory classes. This work was designed to synthesize "N"-hexylcinnamamide through a one-step…

In light of the COVID-19 pandemic situation, the separation of the primary colors of ink markers and food coloring was performed using a simplified column chromatography setup at home to accomplish the educational outcome of the course. The virtual class instruction, for the students enrolled in the "Organic Techniques Laboratory"…

Light emitting diodes have been used to determine Planck's constant in introductory physics laboratories. One common method relies on the energy of the light emitted by the LED and its relation to the energy gap in the solid of which the diode is composed. However, there could be a problem with the data that are collected for this experiment. For…

In this article, we examine the rotation angle dependence of a hand-made fan-type variable capacitor for use in physics experiments in university classes. We made two circular bakelite plates, and the two terminal plates of the capacitor were 90° fan-type copper disks. The capacitance varied linearly with the rotation angle. The standard deviation…

The prompt transfer of cutting-edge science into students' curricula is a challenging task. Often research experiments are too complex or expensive to be translated into a secondary or tertiary education setting. Herein, we introduce a laboratory experiment that translates the recently developed research technique of a wavelength dependent,…
