A procedure to purify anthocyanin, a natural pigment, following a green approach by using macroporous resin and its encapsulation for the maintenance of its stability is described. This laboratory experiment, which describes the benefits of using resin for the purification, is a learning tool for students working in the field on nutraceuticals.…

In recent years, pedagogical advancements have allowed the adoption of more engaging forms of course assignments to help students better understand and communicate chemistry. In this context, informational graphics, known as infographics, emerge as an effective teaching aid in educational settings and in disseminating scientific content to the…

We describe here a 4 hour experimental session based on reaction monitoring of the degradation of an organic pollutant via a Fenton-like reaction. An aqueous solution of p-nitrophenol is treated with hydrogen peroxide and magnetite, and the progress of the reaction is monitored by UV-vis spectrophotometry and/or gas chromatography using an…

A science camp for blind or visually impaired (BVI) students, covering mainly hands-on chemistry experiments, is described. The scientific experiments are detailed, and the feedback of the students is recorded, highlighting the benefits of the camp and its impact. BVI students actively participated in conducting the scientific experiments using…

The COVID-19 pandemic forced the conversion of the quantitative chemical laboratory from a face-to-face format to a distance learning format for the latter half of the Spring 2020 semester. This work provides insight into two different types of assignments given to students during this time: a lab report and a short-answer assignment. At the…

Due to the COVID-19 pandemic, in the spring of 2020 many physics programs were forced to quickly transition all of their classes and laboratories to a completely online learning environment. The need for simple and engaging remote physics laboratories became apparent. One relatively low-cost remote lab system is Macmillan's iOLab device. This…

Three direct complexometric titration methods for bismuth subsalicylate determination in over-the-counter stomach relief caplets and liquids are presented, as well as a UV-vis assay, for use in student laboratories. The main difference between titration methods is the choice of indicator; either xylenol orange (XO), pyrocatechol violet (PV), or…

Active learning pedagogies offer opportunities to increase student engagement and interest in plants. The Mystery Plant Project is a hands-on, semester-long active learning pedagogy I developed for an introductory, undergraduate Plant Biology course. Students investigate various aspects of their mystery plant species using observations, and…

Teacher education needs to combine training in content knowledge, pedagogical knowledge, and pedagogical content knowledge (PCK). One important part of PCK in science education is knowledge about school science practical work to promote learning by scientific inquiry and about the nature of science. In Germany, practical seminars and lab sessions…

This article illustrates the use of Microsoft OneNote as an Electronic Notebook for undergraduate biochemistry lab reports as well as student opinions of this use both before and during the online coursework shift during the pandemic.

More than ever, there is an increasing need for digital experimental learning environments in chemistry. The variety of digital learning approaches provided to students range from simple videos showing experiments to highly interactive virtual laboratories. Regardless of which approach is chosen, a digital learning environment should be adapted to…

Introducing chemical equilibrium concepts in undergraduate general chemistry promotes improved understanding of chemical reactions. We have developed an engaging laboratory experiment exploring the equilibrium of cobalt complexation in alcohols using UV-vis spectroscopy and successfully implemented in a large general chemistry class of 378…

A method to synthesize biaryls through the Suzuki-Miyaura cross-coupling reaction using a recyclable fluorous precatalyst is described. This laboratory experiment, which demonstrates the safety benefits of green chemistry, is integrated into an upper-division course. Besides simply using the catalyst for a reaction, students can reuse the catalyst…

Undergraduate laboratory courses, owing to their larger sizes and shorter time slots, are often conducted in highly structured modes. However, this approach is known to interfere with students' engagement in the experiments. To enhance students' engagement, we propose an alternative mode of running laboratory courses by creating some…

A significant challenge to the community of chemistry education is the creation of materials that can be used in nonscience settings, including those of social science and humanities classrooms. As part of a larger effort to engage new communities in understanding how science data can impact such settings, including in the community, an experiment…
