Sahil Sood; Sean Fang; Alexander Chengyu Wang; Thomas Luong; Justin Keonhyoung Kim; Arkajyoti Sinha; John Jerome; Miriam H. Rafailovich – Journal of Chemical Education, 2023
Hands-on learning is a staple in high school science education, as it provides students with a fast-learning curve and a great degree of field competency. However, due to the safety risks associated with high school students in university chemistry laboratory settings, high school students rarely engage in authentic hands-on chemical learning. To…

Geske, Matthew; Murray-Weston, Crystal; Lelack, Graham – Physics Teacher, 2022
The Wilson cloud chamber, invented in 1911 by Scottish physicist Charles Wilson, is a remarkably simple and effective charged particle detector. Cloud chambers were used regularly in particle physics experiments for decades, until being supplanted by bubble chambers. In this article, we describe a lab activity that is suitable for…

Isabella Guerrero; Charles A. Smith – International Society for Technology, Education, and Science, 2023
In case-based learning, students develop and apply course knowledge to solve tangible and "real life" problems. This practice can enhance student motivation and engagement in the analytical laboratory. In this application of case-based learning students analyze commercially available oils for CBD content. In the state of Texas anyone can…

Xiang Peng; Baochai Xu; Yujie Zeng; Song Xie; Zhanhui Zhang – Journal of Chemical Education, 2024
Removing the pollutants from various wastewater is crucial to the environment, ecology, and humans. However, the pollutants are generally removed by chemical decomposition, which not only consumes a lot of energy but also produces carbon emissions. Electrochemical flocculation is effective to extract pollutant molecules and heavy ions from…

Victoria Borish; H.?J. Lewandowski – Physical Review Physics Education Research, 2024
Instruction in quantum mechanics is becoming increasingly important as the field is not only a key part of modern physics research but is also important for emerging technologies. However, many students regard quantum mechanics as a particularly challenging subject, in part because it is considered very mathematical and abstract. One potential way…
