Nehring, Andreas; Busch, Sebastian – Journal of Chemical Education, 2018
Although many chemistry demonstrations are proposed in educational literature, there are hardly any studies on how demonstrations should be set up in order to support students' perception. Against this background, the aim of the present study was to present and test setup principles for chemistry demonstrations, with regards to indicators of…

Zuidema, Daniel R.; Zuidema, Robert H. – Journal of Chemical Education, 2021
The remote screen control feature in Zoom was used to remotely control instrumentation during an online summer chemistry enrichment session for high school students. This feature was used to draw students into actively participating in chemistry demonstrations where instrumentation was used to gather and analyze data. It can be a challenge to keep…

Nehring, Andreas; Busch, Sebastian – Journal of Chemical Education, 2020
Although demonstrations play a central role in teaching and learning chemistry, the effects of concrete setup principles have rarely been subject to systematic empirical studies. According to the left-to-right principle, the educator should begin with the first step of a reaction in the upper left part of the setup and then place the following…

Kova´cs, Lajos; Betya´r, Ga´bor; Korom, Erzse´bet – Journal of Chemical Education, 2021
Chemistry curricula in part rely on the use of laboratory demonstrations and experiments. The complex nature of this kind of educational activity has been posing challenges from the very early days of teaching chemistry. As chemistry is an experimental science, one possible approach to make the teaching of this subject more efficient is to use…

Eilks, Ingo; Gulacar, Ozcan – Journal of Chemical Education, 2016
One of the topics that chemistry teachers have a great challenge introducing is chemical equilibrium. When being introduced to chemical equilibrium, many students have difficulties in understanding that some reactions do not go to completion, as this contrasts most of their supposed prior experiences in chemistry lessons. Students may also…

Sewry, Joyce D.; Glover, Sarah R.; Harrison, Timothy G.; Shallcross, Dudley E.; Ngcoza, Kenneth M. – Journal of Chemical Education, 2014
Given the emphasis on community engagement in higher education, academic departments need to become more involved in the community. This paper discusses a number of outreach activities undertaken by the chemistry department at Rhodes University, South Africa. The activities range from service learning to community engagement with teachers and…

Stribling, Daniel; Brewer, Christopher R.; Goldsby, Kenneth A. – Journal of Chemical Education, 2021
The mercury beating heart is a dramatic demonstration of redox chemistry that allows for the direct conversion of chemical energy to mechanical energy without involving a machine to accomplish the transfer. Unfortunately, instructors often avoid this demonstration due to difficulties initiating the oscillating redox reaction that drives the…

Sweeder, Ryan D.; Jeffery, Kathleen A. – Journal of Chemical Education, 2013
This article describes the use of a comprehensive demonstration suitable for a high school or first-year undergraduate introductory chemistry class. The demonstration involves placing a burning candle in a container adjacent to a beaker containing a basic solution with indicator. After adding a lid, the candle will extinguish and the produced…

Branan, Daniel; Morgan, Matt – Journal of Chemical Education, 2010
Students everywhere love chemistry demonstrations, especially if they involve explosions. But have you ever wanted to move beyond the "wow" factor and find a way to incorporate active student learning into your demos? What if you could get them to think more deeply about what they're observing, and then find out if they really understand what…

Wang, Tao; Yin, Weidong; Zhang, Shaoxiong; Li, Zhao; Zhang, Shengjun; Zhang, Bo; Ma, Hengchang – Journal of Chemical Education, 2020
This laboratory experiment visually demonstrates the advanced scientific concept of aggregation-induced emission (AIE) using hands-on learning methods. The experiment is divided into two parts: the first period consists of synthesis and isolation of the organic compound 2(TPA-O)-TPE using typical organic chemistry lab techniques; the second period…

Zhang, Jianrui; Antonietti, Markus; Kumru, Baris – Journal of Chemical Education, 2021
Collective motion in living matter is highly intriguing but can also be observed in charged colloidal systems. Collective motion observed in colloidal systems requires extensive material synthesis, external stimuli, and advanced characterization methods that might be highly costly to be employed for teaching. Besides that, colloidal systems can…

Li, Zhuoxuan; Yuan, Ling; Liu, Mengfei; Cheng, Zhenfang; Zheng, Juhua; Epstein, Irving R.; Gao, Qingyu – Journal of Chemical Education, 2021
The Briggs-Rauscher reaction is a popular demonstration to illustrate chemical oscillations in laboratories, classrooms, and public seminars because of its simplicity and visual appeal. Here, we adapt the Briggs-Rauscher reaction to present reaction-diffusion-convection patterns in the undergraduate general or physical chemistry laboratory. By…

Azman, Adam M. – Journal of Chemical Education, 2020
Fast, reliable, well-resolved latent fingerprints can be planted by applying a thin coating of a 50:50 mixture of hand lotion and food-grade protein powder. Fingerprints can be revealed with iodine fuming or ninhydrin staining. This low-cost alternative to commercial latent print pads can be used in a variety of classroom or public settings where…

Pham, Michelle; Foster, Samuel W.; Kurre, Sangeeta; Hunter, Rebecca A.; Grinias, James P. – Journal of Chemical Education, 2021
High-performance liquid chromatography is one of the primary techniques covered in the undergraduate analytical chemistry curriculum. This technology report describes the use of a portable capillary-scale instrument that can provide similar performance to a benchtop instrument but generates less solvent waste and enables operation in nonlaboratory…

There is a growing need for workers with STEM-aligned training in the modern global economy, but a paucity of workers to fill these positions. One important contributor to this issue is low student persistence in STEM. Nontraditional science courses that utilize more active-participation and learning are attractive as tools to increase student…
