Summary: Teaching chemistry to nonscience majors can be challenging due to their negative beliefs and inaccurate knowledge about the subject. In order to address this issue, an inquiry-based approach was implemented, focusing on ubiquitous biodiesel production. Students visited a wastewater treatment plant, collected waste cooking oil, and engaged in guided inquiry-based lab practice to synthesize biodiesel. The activity significantly enhanced students' learning experience and resulted in some students changing their majors to environmental science.

Summary: Electrochemical impedance spectroscopy (EIS) is a rapid and powerful method for evaluating membrane pore structure. This paper suggests a laboratory experiment to improve engineers' understanding of electrochemistry and materials engineering. The experiment focuses on characterizing the pore structure in a membrane using EIS and exploring the correlation between membrane resistance and water flux. Students are trained to collect impedance spectra under different conditions, allowing them to understand the effects of operating parameters on the impedance spectrum.

Summary: The goal of this study was to assess the learning of laboratory techniques by students during online laboratories in response to the transition online caused by COVID-19. The study found that there were gaps in student skills and attempted intervention through the introduction of student-generated video technique quizzes, which resulted in significant improvement in three key areas of laboratory technique skills. The study concludes that even in a completely online laboratory environment, student skills can be developed and improved through targeted interventions using student-generated technique videos.

Summary: This article explores different methods for synthesizing malachite, a green painter's pigment, and evaluates the color of the products using spectroscopy and graphical analysis. Five out of eight methods yielded green products, while three yielded blue products. Thermal decomposition and infrared spectra supported the identification of the green products as malachite.

Summary: Teaching chemistry without access to a traditional laboratory space is a challenge, especially during the SARS-CoV-2 pandemic. Remote learning modules using household adhesives as a platform offer students the opportunity to learn about polymer chemistry and develop research skills. The experiments cover a range of concepts including polymer synthesis, intermolecular interactions, structure-function relationships, providing educators with an additional tool for experimental chemistry education outside the lab.

Summary: Due to the COVID-19 pandemic, many universities worldwide switched to remote learning for the 2020-21 academic year, posing challenges for courses involving hands-on components. This article presents the implementation of a take-home activity kit and laboratory demonstrations for a graduate-level instrument repair and maintenance course, enabling students to engage in hands-on learning remotely. The kit facilitated practical activities at home, while demonstrations were delivered through videos, photos, and instruction manuals. Evaluation through a hands-on practical exam and student survey showed that students found the kit useful and believed it improved their understanding of course topics. The take-home kits and laboratory demonstrations not only fulfilled the course learning objectives but also enhanced student experience and practical skills.

Summary: Hydrogen production through electrochemical water splitting via hydrogen evolution reaction (HER), powered by sustainable energy, is seen as a promising alternative to fossil fuels. A proposed experiment design aims to prepare HER electrodes and evaluate their electrochemical performance for materials science undergraduate students, by integrating knowledge of chemistry, electrochemistry, and materials science with practical application and scientific frontier. The experiment is conducted using conventional equipment and non-toxic chemicals in a materials science comprehensive laboratory. The experimental design covers various aspects, including the mechanism of water splitting, reaction routes in HER, crystal structure of electrocatalyst, electrode preparation protocol, electrochemical evaluation methods, and their relationships, providing students with cutting-edge concepts related to new energy materials and devices, and facilitating the design of electrocatalysts with exceptional comprehensive properties for future green hydrogen production.
