Smith, Catherine J.; Mansfield, Steven J.; Anderson, Edward A.; Burton, Jonathan W. – Journal of Chemical Education, 2019
Organic synthesis in a modern research laboratory uses state-of-the-art equipment to provide inert atmospheres, track reaction progress, and facilitate the purification of intermediates. Such facilities are not available in a high school laboratory. In this paper, synthetic organic chemistry is taken back to basics: A four step total synthesis of…

Schneider, Elia M.; Bärtsch, Amadeus; Stark, Wendelin J.; Grass, Robert N. – Journal of Chemical Education, 2019
A simple synthesis of fluorescent carbon quantum dots from lemon juice is described to introduce advanced high-school students and undergraduate college students to nanoparticle synthesis and quantum dots. The synthesis is based on the carbonization of lemon juice using only a hot plate stirrer. Column chromatography is used to separate different…

Njoki, Peter N. – Journal of Chemical Education, 2019
A laboratory experiment has been developed to illustrate the transformation of silver nanoparticles (Ag NPs) in water containing phosphate anions. The experiment, conducted by high school students, involved hands-on learning to synthesize and characterize Ag NPs via ultraviolet-visible (UV-vis) spectroscopy. This was followed by a UV-vis probe of…

Fernández, Gabriela A.; Ocampo, Romina A.; Costantino, Andrea R.; Dop, Néstor S. – Journal of Chemical Education, 2019
Visually impaired or blind students require adjustments to the traditional hands-on activities and methodological and didactic strategies employed by the teacher. These adaptations are based on multisensory teaching tools, which reinforce the learning of all students in general. This paper presents simple teaching resources that allow students…

Rodenbough, Philip P.; Manyilizu, Majuto Clement – Journal of Chemical Education, 2019
Meeting the challenge of modern global chemistry education requires collaborations from many different actors. Here, we report the development of culturally relevant computer-based lessons on VSEPR and unit cells designed specifically for implementation in the unique environment of East African high schools. The lesson plans use software more…

Hofmann, Andreas; Coster, Mark J.; Taylor, Paul – Journal of Chemical Education, 2019
The interactive generation of chemical-structure diagrams is an integral activity in the study of chemistry as well as in professional chemistry environments. For educational purposes in particular, the existence of suitable software tools free of charge is of great importance. Although a number of free chemical-drawing applications are currently…

O'Donoghue, J. – Journal of Chemical Education, 2019
This work describes the design, building, and testing of miniature, low-cost LED-LDR colorimeters for absorption-spectrophotometry experiments. It also describes using these colorimeters for simplified context-based-learning (CBL) activities in school teaching laboratories and for public-engagement events. The colorimeters are simple and robust,…

Duangpummet, Prempree; Chaiyen, Pimchai; Chenprakhon, Pirom – Journal of Chemical Education, 2019
An inquiry-based laboratory learning unit was designed to enhance high school students' understanding of the application of lipase as a catalyst to synthesize isoamyl and geranyl ester derivatives as well as to promote their understanding and positive perceptions of green chemistry. The learning unit consisted of three laboratories and a final…

Lati, Wichai; Triampo, Darapond; Yodyingyong, Supan – Journal of Chemical Education, 2019
Nanoscience and nanotechnology are the study and application of materials on a nanometer scale. These fields of study aid the developments of innovative technologies that play an important role in our everyday lives. Enabling students to learn these topics makes learning more meaningful and helps prepare them for future technologies. This study…

Kuntzleman, Thomas S.; Bunker, Kasey R.; Bartlett, Ashlee A. – Journal of Chemical Education, 2019
An experiment is described that uses easily obtained materials (glow sticks, chalk, and acetone or alcohol) to separate the dyes contained in glow sticks that actively emit chemiluminescent light. The experiment is very easy to carry out, making it amenable for students to perform in laboratory or outreach settings. The separation occurs fast…

Stowe, Ryan L.; Herrington, Deborah G.; McKay, Robert L.; Cooper, Melanie M. – Journal of Chemical Education, 2019
Widespread adoption of the Next Generation Science Standards (NGSS) has created a need to carefully consider how chemistry curricula should support students in understanding the world in terms of atomic/molecular behavior. We argue that Standards-aligned coursework should be "core-ideas centered" due to evidence that curricula embedded…

Bierenstiel, Matthias; Snow, Kathy – Journal of Chemical Education, 2019
The Periodic Table of the Elements (PTE) is arguably one of the most central topics in chemistry. This article provides a critical review of current teaching practices of the PTE to high-school students and undergraduate university students. It also provides a new teaching model, the "periodic universe", for understanding of the PTE…

Bibic, Lucka; Druskis, Justinas; Walpole, Samuel; Angulo, Jesus; Stokes, Leanne – Journal of Chemical Education, 2019
Virtual reality (VR) technology has been capturing the public imagination for decades. VR software applications that allow for interactive immersion are emerging as a renowned medium in many areas, including educating the public in biochemistry-related subjects via public engagement events. This report provides information about an immersive,…

Stowe, Ryan L.; Herrington, Deborah G.; McKay, Robert L.; Cooper, Melanie M. – Journal of Chemical Education, 2019
Connecting the behavior of invisible (to the naked eye) particles governed by the principles of quantum mechanics to the world we can see and touch requires a host of inferences, almost none of which can be extrapolated from experience. Molecular-level sensemaking thus relies upon intellectual resources that must be developed in large part by…

Nalliah, Ruth E. – Journal of Chemical Education, 2019
In selecting from a repertoire of traditional kinetics experiments, an instructor often has to choose among having students gain experience with the graphical method, the method of initial rates, or a temperature-dependent experiment in which students construct an Arrhenius plot. This paper presents an environmentally friendly bleaching reaction…
