Cola beverages are widely consumed and popular among students; they can be used as safe reagents to replace toxic chemical dyes. In this study, a safe and improved experiment is described, which successfully demonstrates Beer's law and adsorption process using activated carbon as the adsorbent and cola as the adsorbate. The results of this study…

A relatively large number of organic and inorganic chemistry reagents are air- or moisture-sensitive, and undergraduate students should be trained in their use. When handling such reagents, it is important to select the correct syringe and to use that syringe correctly. We have found that the best syringe for use in an undergraduate setting is a…

Chemical spillage has been measured for undergraduate students undertaking a laboratory practical designed to help develop their chemical handling skills. There was a low correlation found between the amount of chemical spilled and the ability to accurately carry out the primary goal of the experiment, which was to measure the concentrations of…

Educational resources that cover essential knowledge related to chemistry safety rules are openly accessible on the CHIMACTIV website (http://chimactiv.agroparistech.fr/). Organized into two online tracks, the content covers personal and collective protections, first aid, as well as the handling of hazardous chemicals. Being interactive and…

Academic standards in the United States advocate for the integration of science, and technology and engineering (T&E) content and practices within the elementary grades (ITEEA, 2020; NGSS Lead States, 2013). However, elementary educators often receive limited preparation for developing and facilitating safer hands-on science and T&E…

Chemical engineering students need to be prepared to make process safety decisions in industry. Through analysis of the decision-making process of senior chemical engineering students, we found students would rather be "better safe than sorry" and did not often acknowledge complexities associated with their decisions. Their decisions…

To prove that oxygen is irreversibly consumed in the blue bottle reaction, a manometer or a plastic bottle was used to show a permanent reduction in the gas pressure in a reaction vessel. This demonstration may be misleading because the change in gas pressure can be attributed to a number of other factors such as temperature change and involvement…

According to previous studies, traditional laboratory safety courses are delivered in a classroom setting where the instructor teaches and the students listen and read the course materials passively. The course content is also uninspiring and dull. Additionally, the teaching period is spread out, which adds to the instructor's workload. As a…

Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…

While lab accidents that involved personal injuries or significant property damage are required to be reported by law, many minor lab incidents or near misses are less frequently reported, especially in an academic research environment. However, public awareness of these stories and incidents create valuable learning opportunities and can prevent…

This article introduces a novel experiment that involves vitrimers, a new type of polymer, in polymer chemistry and physics lab courses for undergraduate students. Vitrimers are permanently cross-linked networks that can be reprocessed under certain external stimuli. Therefore, they combine the advantages of traditional thermoplastics (excellent…

A comprehensive educational framework is provided by the Conceive-Design-Implement-Operate (CDIO) which is particularly relevant to engineering and applied sciences. This paper investigates the application of the CDIO approach in the field of chemistry pedagogy in Vietnam focusing on its adaptability to the current educational demands and its…

This paper reports an immersive virtual reality lab (iVRLab) training environment that offers college students an immersive and embodied experience in engineering lab work. The iVRLab provides a simple and safe environment for students to learn the complex lab operations to process and prepare silicon wafers. It features highly embodied…

The chemistry of metal-organic frameworks (MOFs) has the potential to introduce high school and undergraduate students to the fundamental chemical principles of structure and bonding, enhance the development of skills in synthesis and crystal growth, and promote hands-on experience with gas capture and host-guest chemistry of emerging materials…

General safety and chemical training of undergraduate students is typically held at the first-year level. In this technology report, we propose a flexible strategy to improve students' general knowledge of safety for a second-year inorganic chemistry laboratory. The strategy is composed of an online interactive revision approach through the…
