The main difficulty in studying molecular symmetry is the mental manipulation of molecules when searching for symmetry. Numerous methods of teaching molecular symmetry require students to identify symmetry elements of objects or molecules. As an alternative, we propose activity that identifies symmetry using elements outside the objects, together…

Amy Lang – Afterschool Matters, 2024
In light of the proven benefits of high-quality afterschool STEM programming for teens, the author worked with colleagues at University of Maryland Extension to institute the Pollinator Ambassador program. The program was launched through a county-based 4-H program at a partner site in a community outside Washington, DC. Following the 4-H Thriving…

Fuwa Yoshioka; Masato Takada; Rui Itoh; Airi Uzawa; Junpei Hayakawa – Journal of Chemical Education, 2024
Xerogels, exemplified by silica gel, are substances formed by drying gels, resulting in a loss of their internal solvents. Understanding the production and properties of xerogels is crucial, owing to their widespread applications. Xerogel chemistry is widely utilized in several substances; therefore, understanding this chemistry is extremely…

Neuenschwander, Dwight E. – Physics Teacher, 2020
Previous generations of physics students learned how common machines work, as evidenced by their textbook illustrations. Such understanding of machines that daily life depends on seems to be evaporating. In response, for two decades I have conducted an introductory physics "engine cadaver lab." It offers opportunities for hands-on…

Manninen, Marianna; Vesterinen, Veli-Matti; Salminen, Juha-Pekka – Journal of Chemical Education, 2020
The autumnal leaf color change is a familiar phenomenon to most students living in temperate climate zones. The extraction and analysis of the pigments of the autumn leaves provide an engaging way to study the phenomenon utilizing both simple as well as more sophisticated analytical methods. In this laboratory experiment, students extract the red…

Many simple chemical reactions produce an audible fizz due to the formation of gases, such as oxygen, hydrogen, or carbon dioxide. A hands-on activity based on perceiving these audible chemical changes is presented. The relative quality of fizz due to the formation of gases in a chemical reaction was determined by visually impaired middle and high…

Non-rigid spatial thinking, or mental transformations where the distance between two points in an object changes (e.g., folding, breaking, bending), is required for many STEM fields but remains critically understudied. We developed and tested a non-rigid, ductile spatial skill measure based on reasoning about knots with 279 US adults (M = 30.90,…

Tiano, Martin; Roose, Max – Journal of Chemical Education, 2022
We describe here a 4 hour experimental session based on reaction monitoring of the degradation of an organic pollutant via a Fenton-like reaction. An aqueous solution of p-nitrophenol is treated with hydrogen peroxide and magnetite, and the progress of the reaction is monitored by UV-vis spectrophotometry and/or gas chromatography using an…

Hands-on labs are a critical component of biomedical engineering undergraduate education. Due to both the pandemic and the growing interest in online education, we developed a Do-it-yourself Electrocardiogram (DIY EKG) project. The Arduino-based DIY EKG kit instructed students how to build a circuit to obtain their own EKG and then analyze their…
