Understanding the basics of d-electron configuration and the spin state of coordination complexes are essential elements of undergraduate inorganic chemistry. However, students in these courses find it difficult to conceptualize the ideas. Here, we have developed an undergraduate laboratory experiment that allows students to systematically…

An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases "initiative's" Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent for biological…

Moya, Antonio Angel – Physics Teacher, 2022
Resistor--capacitor (RC) circuit labs help students, but most courses don't include them because of complications and cost. This work presents an easy and inexpensive Arduino-based lab on the charge and energy transfer between two capacitors with different values of the initial electric charge when they are connected through a resistor. Capacitors…

Electrochromism encompasses reversible changes of material's optical properties (color, opacity) under the influence of an external electric current or applied voltage. The effect has been known for decades, but its importance continues to grow due to the rapid development of smart systems and the accompanying demand to build devices that consume…

In this laboratory experiment, students modify a series of surfaces and explore the effects of varying surface chemistry and texture on wettability by different probe liquids. Students begin by building a simple contact angle goniometer utilizing their mobile phone cameras. Next, they contrast the wettability of planar glass substrates…

Patrick I. T. Thomson; Paul Lamie – Journal of Chemical Education, 2022
This work further implements the "elements of inquiry" approach in a first-year undergraduate laboratory course, in a two-part inquiry sequence. In the first part of the sequence, students iteratively develop a "best-practice" TLC procedure. In the second part, students iteratively optimize a simple organic reaction using TLC,…

The American Chemical Society advocates a shift from rule-based to risk-based safety education for chemistry graduates, emphasizing meaningful student engagement in the risk assessment process for laboratory work. To implement this paradigm shift, we introduced RAMP (Recognize Hazards, Assess Risk, Minimize Risk, and Prevent Emergencies)-based…

CACAO (Chocolate Across the Curriculum and Outreach) is a vertical curriculum augmentation designed to help students across the ChE undergraduate program. The students use a chocolate-based food engineering lab to make connections between core chemical engineering topics using hands-on and project-based learning. Costs to create this component are…

Jennifer Harmon – Journal of Family and Consumer Sciences, 2024
The interdisciplinary nature, breadth of topics and frequently evolving industries Family and Consumer Sciences (FCS) courses engage with make it difficult for one approach to be appropriate in all circumstances. The Advanced Textiles, 4000 level course participating in this study focused mainly on color science, dyes and dyeing, in addition to…

Titration is an important experimental skill that every chemistry educator and learner must master. Titration is often the method of choice in the science laboratory courses in secondary and postsecondary schools. During acid-base titration, chemistry learners are always told about salt formation. However, a practical visualization of the salt…

This study aimed to determine the effect of using a virtual anatomy system (VAS) on student learning with regard to reproductive system with respect to the acquisition of misconceptions. This study used an experimental method by comparing the results of the class learning using virtual laboratory media with a control class. The result showed that…

We present a simple smartphone-based protocol for the estimation of the critical micelle concentration (CMC) of surfactants. The protocol is based on contact angle measurements from the smartphone-captured images of differently concentrated surfactant solution droplets mounted over a naturally existing or chemically synthesized superhydrophobic…

A laboratory experiment was designed to introduce the practical application of biocatalysis in Bachelor and Master courses in biotechnology and medicinal chemistry, respectively. To this aim, the lipase from "Candida rugosa" was characterized (protein concentration and activity), immobilized on a carrier (by hydrophobic adsorption), and…

Engaging in argument from evidence is a fundamental science practice. However, preservice elementary teachers have difficulty constructing arguments. They need effective experience with argument construction in science. Written argumentation is crucial in the process of science learning. One of the approaches for learning science through…

Virtual laboratories (VLs) enable students to experiment, analyze data, or interact with digital content in a nonphysical space. VLs include simulations, electronic notebooks, videos, and augmented reality. As part of the "VL Project," comprising five academic institutions in Ireland, we sought to determine how VLs might enhance…
