Jiang, Rundong; Li, Chenglu; Huang, Xudong; Sung, Shannon; Xie, Charles – Science Teacher, 2021
Telelab, an implementation of remote labs 2.0, is open-source and freely available for non-commercial use. The platform consists of sensors that collect data, smartphone apps that transmit data and videos from anywhere, and a web app that provides a user interface to view, analyze, and control remote experiments. Based on this platform, any…

Agliolo Gallitto, Aurelio; Zingales, Roberto; Battaglia, Onofrio Rosario; Fazio, Claudio – Physics Education, 2021
Student understanding of the laws that describe the flow of a fluid is often hampered by a defective knowledge of basic classical mechanics (kinematics, statics, dynamics, and conservation laws) and by wrong common-sense ideas about quantities related to fluids, such as velocity and pressure. A pedagogical discussion about the Venturi effect,…

Veith, Sonja Isabel; Friege, Gunnar – Physics Education, 2021
Sound is an interesting topic for physics lessons at all ages. However, it is difficult to illustrate this ubiquitous phenomenon and many models do not adequately represent the properties of sound and thus promote unwanted conceptions. The experiment presented here avoids this by visualising sound itself with the help of the schlieren technique.…

González-Flores, Diego; Fernández, Gabriela; Urcuyo, Roberto – Journal of Chemical Education, 2021
Electrochemical and spectroelectrochemical techniques are very important for characterizing energy materials. In the search for new sources of renewable energy, water splitting for hydrogen production and CO[subscript 2] reduction is attracting significant attention. These applications require efficient and durable catalysts and a detailed…

Oss, Stefano – Physics Education, 2021
An apparatus of the 70s for measuring thermal conductivity in different materials is used to visualize, through an infrared thermal imaging approach, temperature fields and the heat diffusion process. The observed temperature profiles also suggest solid grounds for a fair mathematical modelling of this phenomenon.

Yerzhenbek, Bulbul; Sydykova, Zhainagul; Zhadrayeva, Larissa; Zhumaliyeva, Lyazzat; Yessenova, Mariya – Cypriot Journal of Educational Sciences, 2022
Improving the education quality, its compliance with modern requirements is closely related to the assimilation of scientific concepts by schoolchildren, which is one of the most important components of the scientific knowledge element. The article aims to present a methodology for the students' formation of physical concepts. The stages of…

Lindén, Johan; Fogde, Anna – Physics Education, 2022
An ordinary soap bubble immersed in a pure carbon-dioxide atmosphere, created e.g. by sublimating chunks of dry ice (solid CO[subscript 2]), will expand within a few minutes to a volume exceeding the original one with a factor of almost ten. Considering that the bubble simultaneously experiences a cooling of ~30 ?C one would perhaps expect a tiny…

G., Abigail Jennifer; Thomas, Midhun George; Solomon, Rajadurai Vijay – Journal of Chemical Education, 2022
The sudden COVID-19 outbreak has obstructed the conventional method of teaching causing a mandated shift to virtual platforms. A developing country like India which predominantly depended on conventional methods of teaching and learning in the pre-COVID era is gradually gaining success in effectively transitioning into virtual classrooms with the…

Baqi, Younis – Journal of Chemical Education, 2022
A fast, operationally simple, and reproducible synthetic protocol for anthraquinone dyes (AQDs), suitable for upper-division undergraduate industrial and organic chemistry laboratory courses, has been developed. This experiment is composed of three stages; the first step deals with the synthesis of AQDs, followed by a purification step, and…

Johnson, Bettie Obi; Golonka, Annette M.; Emmanuel, Khalisha A.; Ponnarasu, Jeffshan J.; Pryor, Joseph E. – Journal of Chemical Education, 2022
A novel undergraduate analytical chemistry experiment involving the identification and quantification of linalool in essential oils was developed. The experiment uses the internal standard method with headspace solid phase microextraction (SPME) and gas chromatography--mass spectrometry (GC-MS). This method is applicable to any linalool-containing…

Wang, Jixin; Zhou, Wenshui; Yu, Mei; Zhu, Zheng; Li, Ying – Journal of Chemical Education, 2022
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…

Patchett, Ruth; Watson, Robyn; Davies, Joe; Schnepp, Zoe – Journal of Chemical Education, 2022
Chemistry experiments are challenging for people with vision impairment (VI) as results often rely on visual observations such as a color change. This puts pupils with VI at a disadvantage both in their scientific learning and in their development of broader life skills. In this paper, we describe a simple and low-cost experiment on the adsorption…

Khalid, Habiba; Amin, Farrukh Raza; Chen, Chang – Biochemistry and Molecular Biology Education, 2022
An integrated laboratory experiment was designed for introducing biochemistry students to basic static biochemistry to deepen their understanding on the properties and analysis of biomolecules such as total carbohydrates, lipid, protein, and protein-constituent amino acids. Food represents a very important source of biomolecules of technological…

dela Cerna, Mark Vincent – Journal of College Science Teaching, 2022
A rudimentary level of scientific literacy is necessary in the general public. At the undergraduate level, this literacy can be achieved through general education courses offered in areas of natural sciences. Over the past several years, practical courses have been developed to make the teaching of chemistry concepts in the laboratory more…

Ha, Hye Jin; Jang, Taehun; Sohn, Sang Ho – Physics Education, 2022
In this study, we derived several formulas for the currents induced in a circular loop by a magnet connected to a spring-based simple harmonic oscillation system. In addition, we conducted an experiment for measuring the induced currents and compared the results with the theoretical prediction. It was confirmed that the prediction from the derived…
