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…

This report presents a miniproject for teaching sustainability through the production of adsorbents from sewage sludge. The activity was tested during the Physical Chemistry II portion of an Agro-Industrial Engineering Course and lasted 4 weeks. The activities developed by the students included preparing the adsorbents ("in natura,"…

Due to a growing awareness of environmental issues, green chemistry concepts are increasingly being incorporated into the undergraduate organic chemistry lecture and laboratory component. This minireview summarizes environmentally friendly organic chemistry experiments suitable for undergraduate laboratories. Whenever feasible, LD[subscript 50]…

Resonant cavity perturbation as a means to measuring permittivity has been used since the early 1940s. It is attractive because it is non-contact, non-destructive and experimentally simple. Only recently, however, has the cost of a small analyser board become acceptably low that experiments can be carried out in schools and colleges. Using the TE…

Capstone teaching laboratory activities can serve as a crucial part of the undergraduate learning experience. With this in mind, a laboratory activity that combines synthesis and multiple characterization techniques has been developed for an upper-division, laboratory-based inorganic course. Complexes of Cu(II) and Ni(II) of the amino acid glycine…

Introductory physics laboratory experiments have typically been employed to reinforce classroom instruction instead of teaching students experimental design. Recent research has shown that lab experiments that focus on experimental practices are more effective at teaching students physics concepts. The experiment described in this paper has been…

In class environments, the flipped classroom (FC) model has been found to increase students' attitudes, achievement, and motivation. However, the practical effects of the FC model in laboratory environments have not been introduced into the literature. Therefore, in this study, the effects of the FC model on the laboratory self-efficacy skills and…

It is unclear if the transition from traditional, in-person physiology laboratories to virtual alternatives has educational impacts on students. This study used a systematic review to critically evaluate research papers that investigated the effectiveness of virtual physiology laboratories for student learning. Eleven studies, retrieved from the…

The bromination of six isomeric alcohols is adapted to a discovery-based organic chemistry laboratory experiment, whereby students are provided an alcohol starting material and are charged with determining the product or product mixture produced using relevant spectroscopic data. The experiment solidifies NMR analysis skills while reinforcing the…

We have developed a new foundation-level course at our institution that links the concept of chemical equilibria from four of the traditional subdisciplines (analytical, biochemistry, inorganic, and physical). The course, entitled Solution and Solid State Chemistry (CHEM 210), is designed to serve our chemistry and biochemistry majors, as well as…

This laboratory experiment introduces upper-division undergraduate analytical chemistry students to liquid chromatography-tandem mass spectrometry (LC-MS/MS) in a forensic application: the analysis of cocaine and metabolites of cocaine in simulated serum ostensibly from drug overdose victims. For this investigation, students developed the…

This work presents a simple protocol that demonstrates the use of an inexpensive household carbon monoxide detector as a useful tool to detect the release of carbon monoxide gas from thermal cheletropic decarbonylation reactions. The carbon monoxide detection method described has been employed in a short series of reactions used in a university…

This three-part laboratory experiment investigates key aspects of the Buchwald-Hartwig amination cross-coupling reaction through guided-inquiry learning strategies. The first part of this experiment utilizes high-throughput experimentation techniques to reinforce, explore, and extend fundamental concepts that are represented in the classroom,…

Many universities resort to online teaching due to COVID-19 pandemic. It is a challenging endeavor, especially in Molecular Biology courses that require lab access. Mock grant application roleplay is one alternative to lab-based activities. Students are engaged in three aspects: (i) targeted literature review, (ii) research proposal writing and…

A traditional laboratory course with the primary learning outcome of improving students' theoretical knowledge has received much criticism over the years due to the lack of evidence that these goals have achieved. We report our efforts to redesign a traditional first-year organic and inorganic (also known as synthetic) laboratory course from…
