Cross, Rod – Physics Education, 2022
Experimental results are presented concerning the motion of a ball that bounces up an incline a few times then bounces back down again. The number of bounces up the incline is typically small since the speed of the ball in a direction parallel to the incline decreases rapidly, not only during each bounce but also while the ball is in the air. The…

Jake Morris; Cameron Stewart; George N. Harakas – Journal of Chemical Education, 2022
The overhead mechanical stirrer is a versatile and valuable tool for the laboratory. Even a low-end mechanical stirrer is rather expensive and can pose serious safety concerns for use by high school or undergraduate students. The construction and application of a low-cost overhead mechanical stirrer is described in this work. The mechanical…

Green, Michael E. – International Society for Technology, Education, and Science, 2021
In a chemistry course for students not majoring in science, there is more to learn than some memorized facts: the student can find, in most non-major chemistry texts, the definition of atomic number, something about chemical bonding, and names of some classes of chemical compounds. Where facts come from and how accurately they are known are often…

Ristanto, Sigit; Nugroho, Waskito; Sulistya, Eko; Suparta, Gede B. – Physics Education, 2022
Measuring the 3D position at any time of a given object in real-time automatically and well documented to understand a physical phenomenon is essential. Exploring a stereo camera in developing 3D images is very intriguing since a 3D image perception generated by a stereo image may be reprojected back to generate a 3D object position at a specific…

Doucette, Danny; Daane, Abigail R.; Flynn, Angela; Gosling, Chris; Hsi, Dana; Mathis, Clausell; Morrison, Andrew; Park, Shinae; Rifkin, Moses; Tabora, Johan – Journal of Chemical Education, 2022
There is a wide variety of ways for instructors to seek to improve diversity, equity, inclusion, and respect (DEIR) in chemistry through their instruction. One way is to talk with students explicitly about equity and injustice in science. We propose a curricular framework for teaching about equity as a way to improve DEIR in science classes at the…

White, A. E. – Physics Education, 2022
This paper presents the design and reports on the use of a simple and inexpensive cloud chamber kit that is compatible with active learning, experiential learning, and project-based learning strategies. The kit was developed for use in a first-year undergraduate nuclear science seminar class at a university in the US. Diffusion cloud chambers are…

Priya Yadav; Harshita Laddha; Madhu Agarwal; Ragini Gupta – Journal of Chemical Education, 2022
A smartphone-based digital imaging method has been successfully introduced in an undergraduate laboratory class to quantify fluoride ions in water. Students first synthesized the chemosensor (E)-2-(1-(6-nitro-2-oxo-2H-chromen-3-yl)ethylidene)-N-phenylhydrazine-1-carbothioamide (CT) via an eco-friendly and green microwave-assisted protocol and…

Eric Kincanon – European Journal of Physics Education, 2022
Teaching upper division statistical physics can often be clouded by the theory and complex examples used. To better help students appreciate the fundamental statistical concepts and how they are connected to thermodynamic principles this paper suggests using a simple abstract model. Using Atkins' Model students can see these ideas clearly…

Chukwuneke, Chikaodili E.; Madu, Joshua O.; Agboola, Bolade O. – Journal of Chemical Education, 2021
Trace metals when present in crude oil or fuels are of economic significance in refining and to the combustion engines that use them. Herein, we develop a laboratory activity that trains students on how to analyze crude oil samples for ash and trace metal content while giving them the opportunity to acquire skills needed as a quality control…
