Mohan, Ram S.; Mejia, Maria P. – Journal of Chemical Education, 2020
Due to a growing awareness of environmental issues, green chemistry concepts are increasingly being incorporated into the undergraduate organic chemistry lecture and laboratory component. This minireview summarizes environmentally friendly organic chemistry experiments suitable for undergraduate laboratories. Whenever feasible, LD[subscript 50]…

Pili, Unofre B. – Physics Education, 2020
Using Tracker, a popular video-based physics modeling tool, the position-time data of magnetically damped oscillations of a simple pendulum are acquired. Eddy currents are generated on an aluminum sheet as the magnetic pendulum bob passes over it and the induced magnetic field opposes that of the magnetic bob. This causes the damping. A…

Thompson, Frank – Physics Education, 2020
Resonant cavity perturbation as a means to measuring permittivity has been used since the early 1940s. It is attractive because it is non-contact, non-destructive and experimentally simple. Only recently, however, has the cost of a small analyser board become acceptably low that experiments can be carried out in schools and colleges. Using the TE…

Ermis, Ferhat; Karaman, Ibrahim – Physics Education, 2020
This study provides information about the formation of colours with an experimental activity based on the reflection of coloured lights from pigments. The activity shows the formation of colour in a simple and entertaining way. The lights are reflected by being changed by different coloured pigments. This activity provides an opportunity to…

Ogawara, Yasuo – Physics Teacher, 2020
When we teach thermodynamics, a vacuum container used to keep food isolated from air is a cheap and interesting teaching device. There are some experiments already described in the literature and we can also find videos of demonstrations on YouTube. At the same time, there is increasing interest in how to utilize smartphones in physics…

Drake, Dereth J.; Epperson, Christiana G.; Burks, Savanna L. – Physics Teacher, 2020
Introductory physics laboratory experiments have typically been employed to reinforce classroom instruction instead of teaching students experimental design. Recent research has shown that lab experiments that focus on experimental practices are more effective at teaching students physics concepts. The experiment described in this paper has been…

Ramos, L. M.; Reis, C. R. N.; Calheiro, L. B.; Goncalves, A. M. B. – Physics Education, 2021
Using a joystick module, we followed the movement of a chaotic magnetic pendulum. The pendulum bar was attached to a joystick that served as a pivot point and biaxial angular motion sensor. Using an Arduino board, we could follow the position as a function of time along both the "x" and "y"-axis and draw a graph showing the…

Çelik, Harun; Pektas, Hüseyin Miraç; Karamustafaoglu, Orhan – Electronic Journal for Research in Science & Mathematics Education, 2021
In class environments, the flipped classroom (FC) model has been found to increase students' attitudes, achievement, and motivation. However, the practical effects of the FC model in laboratory environments have not been introduced into the literature. Therefore, in this study, the effects of the FC model on the laboratory self-efficacy skills and…

O'Reilly, Matthew C.; Stoffregen, Stacey A.; Peterson, Karl P.; Maddox, Mitchell P., III; Schrank, Cordell – Journal of Chemical Education, 2021
The bromination of six isomeric alcohols is adapted to a discovery-based organic chemistry laboratory experiment, whereby students are provided an alcohol starting material and are charged with determining the product or product mixture produced using relevant spectroscopic data. The experiment solidifies NMR analysis skills while reinforcing the…

Miles, Deon T.; Joslin, Evan E. – Journal of Chemical Education, 2021
We have developed a new foundation-level course at our institution that links the concept of chemical equilibria from four of the traditional subdisciplines (analytical, biochemistry, inorganic, and physical). The course, entitled Solution and Solid State Chemistry (CHEM 210), is designed to serve our chemistry and biochemistry majors, as well as…

Vergne, Matthew J. – Journal of Chemical Education, 2021
This laboratory experiment introduces upper-division undergraduate analytical chemistry students to liquid chromatography-tandem mass spectrometry (LC-MS/MS) in a forensic application: the analysis of cocaine and metabolites of cocaine in simulated serum ostensibly from drug overdose victims. For this investigation, students developed the…

Calheiro, L. B.; Freitas, W. P. S.; Martins, C. A.; Goncalves, A. M. B. – Physics Education, 2021
We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an…

Wathen, Bailee; Lanehart, Emily; Woodis, Lena A.; Rojas, Anthony J. – Journal of Chemical Education, 2021
This three-part laboratory experiment investigates key aspects of the Buchwald-Hartwig amination cross-coupling reaction through guided-inquiry learning strategies. The first part of this experiment utilizes high-throughput experimentation techniques to reinforce, explore, and extend fundamental concepts that are represented in the classroom,…

Gorman, Stephen A.; Holmes, Kimberly; Brooke, Gemma; Pask, Christopher M.; Mistry, Nimesh – Journal of Chemical Education, 2021
A traditional laboratory course with the primary learning outcome of improving students' theoretical knowledge has received much criticism over the years due to the lack of evidence that these goals have achieved. We report our efforts to redesign a traditional first-year organic and inorganic (also known as synthetic) laboratory course from…

The Making Introductory Courses Real while Online (MICRO) laboratory project was developed to meet the need for hands-on experiments, focused on topics in analytical chemistry, to be delivered safely remotely or in a socially distanced in-person lab. Unlike more traditional lab experiments, MICRO laboratories use only microgram or nanogram amounts…
