Young, Kaisa E.; Young, Chadwick H. – Physics Teacher, 2019
Two of the most fundamental skills that students acquire in introductory undergraduate physics laboratory courses are how to accurately plot data and interpret the physical meaning of linear graphs. We redesigned our graphing skills lab with an open-ended approach designed to promote inquiry in graphical analysis and to address specific areas of…

DiLisi, Greg – Physics Teacher, 2019
The author, Greg DeLisi, a professor at John Carroll University, is always looking for ways to bring current events into his introductory physics classroom or laboratory. He is especially interested in finding examples where basic principles of physics can be used to cast skepticism on assertions made by celebrities, politicians, or professional…

Kean, Kelsey M.; van Zee, Kari; Mehl, Ryan A. – Journal of Chemical Education, 2019
The content and design scheme for a readily adaptable, research-based laboratory course in chemical biology are presented. In this course, students interrogate protein structure and function using the site-specific incorporation of noncanonical amino acids by genetic code expansion. The relatively new field of genetic code expansion enables…

Limpanuparb, Taweetham; Kanithasevi, Siradanai; Lojanarungsiri, Maytouch; Pakwilaikiat, Puh – Journal of Chemical Education, 2019
We discuss the use of a simple piece of equipment made of a 50 mL syringe attached to a 2 mL graduated pipet to demonstrate Boyle's law and Charles's law. A plot of the hydrostatic pressure against the reciprocal of the volume of the gas read from the equipment is linear as discussed in the paper and gives the atmospheric pressure at the…

Elliott, Leslie Atkins; Sippola, Elizabeth; Watkins, Jeffrey – Journal of Chemical Education, 2019
In this article, we describe how the Gaussian Gun, a simple configuration of magnets and ball bearings, can be leveraged to connect ideas from physics to representations and ideas that are central to chemistry and challenging for students to learn. In particular, we show how the Gaussian Gun, an arrangement of ball bearings and magnets, models…

Grosso, Carla; Liber, Marta; Brigas, Amadeu F.; Pinho e Melo, Teresa M. V. D.; Lemos, Américo – Journal of Chemical Education, 2019
Regioselectivity in hetero Diels-Alder reactions can be observed in a simple reaction between a nonsymmetrical heterodiene and an unsymmetrical heterodienophile. A 9 h and easy to implement laboratory experiment is described, in which students can observe the regioselectivity of inverse "electron-demand" hetero Diels-Alder reactions of…

Calcabrini, Mariano; Onna, Diego – Journal of Chemical Education, 2019
The study of gels and their properties is a compelling topic both technologically and scientifically, and should therefore be emphasized in chemistry and material science syllabuses. In the present laboratory experiment, we propose two experiences, aimed at introducing gelation and gel transport properties using silica gels made from sodium…

Kwan, Ann H.; Mobli, Mehdi; Schirra, Horst J.; Wilson, Jennifer C.; Jones, Oliver A. H. – Journal of Chemical Education, 2019
Magnetic resonance is a powerful technology that has had a major impact across the physical, life, and medical sciences, from chemistry to medical imaging, with ever-expanding applications in new areas as diverse as mining and food science. It is, however, also a difficult subject to teach, as the theory is complex and requires some familiarity…

Esselman, Brian J.; Block, Stephen B. – Journal of Chemical Education, 2019
The VSEPR model has well-established limitations in its ability to represent accurate molecular and electronic geometries of simple molecules, which can create a significant need for students to relearn structure and bonding concepts in organic chemistry. We present an alternate method for describing molecular geometries and electronic structures…

de Jesus, V. L. B.; Pérez, C. A. C.; de Oliveira, A. L.; Sasaki, D. G. G. – Physics Education, 2019
Currently, the number of smartphones with an embedded gyroscope sensor has been increasing due games whose performance relies on 3D augmented reality. In general, teaching papers on the gyroscope sensor address very simple spatial configuration, where the fixed rotation axis coincides to the z-axis of the smartphone. This work presents five…

Lopper, Matthew E. – Journal of Chemical Education, 2019
This paper describes a responsive, digital periodic table that has been specifically designed as a visual aid for high school or college chemistry classrooms and lecture halls. The periodic table runs in a web browser and can therefore be used in any classroom that has a digital projector and screen. It features click-to-highlight table cells that…

Raff, Lionel M.; Cannon, William R. – Journal of Chemical Education, 2019
For 26 years, it has been assumed by some that the thermodynamics of open-system biochemical reactions must be executed by performing Legendre transformations on the terms involving the species whose concentrations are being held fixed. In contrast, standard nontransformed thermodynamics applies to chemical processes. However, it has recently been…

Gascon, Katherine N.; Weinstein, Steven J.; Antoniades, Michael G. – Journal of Chemical Education, 2019
The effect of surfactant adsorption on surface tension, as well as associated thermodynamic concepts are introduced in a laboratory experiment designed for undergraduate students. Using a reliable and accessible method, students measure the surface tension of aqueous solutions at different concentrations of sodium dodecyl sulfate. Students collect…

Croisant, Michael; Bretz, Stacey Lowery; Konkolewicz, Dominik – Journal of Chemical Education, 2019
The ACS Guidelines for bachelor's degrees in chemistry call for the curriculum to include polymer chemistry principles and the synthesis of different classes of macromolecules. Organic chemistry can provide an important introduction to polymer chemistry principles, and photochemically induced radical polymerization is one method for generating…

Saba, Shahrokh; Corozo-Morales, Ariel – Journal of Chemical Education, 2019
A pedagogically useful undergraduate organic-chemistry-laboratory experiment has been developed that involves the synthesis of two structurally simple, achiral "O,O"- and "N,N"-acetal substrates with no stereocenters. The experiment introduces students to a "new" and more effective variant of classical acetal…
