In the 1930s, the teaching staff of the University of Chicago devised a clever way to deliver experimental data to their introductory students without meeting them in the laboratory. The university's curriculum included a required Introductory Course in the Physical Sciences. There were probably too many students to allow for a standard…

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…

This paper analyzes the role of the university research laboratory in university-industry interactions for technology transfer. Specifically, it examines how the laboratory research infrastructure, team qualification and local incentives influence knowledge and technology transfer in biotechnology. Despite the importance of the research laboratory…

Modeling is an important tool in science teaching and learning. Constructing a model instead of replicating one is more meaningful and better supports student learning than analyzing premade models (Firooznia 2015; Gouvea and Passmore 2017; Takemura and Kurabayashi 2014). Models include physical replications of a scientific phenomenon or analyzing…

Using crystal structure data, site directed mutagenesis, and real-time kinetic assays, students designed, expressed, and purified engineered mutants of human insulin-degrading enzyme (IDE). Students designed their own IDE mutants following "in silico" analysis, used inverse PCR to generate mutant plasmid expression constructs, expressed…

This paper shows a method for integrating computer programming into a standard physical chemistry laboratory sequence to augment student data analysis abilities and allow them to carry programming skills forward to other courses. The Python programming language is used, taking advantage of the pedagogical benefits of Jupyter notebooks, primarily…

This article is focused on the effectiveness of an innovative research-based learning model that employs chemistry-based research projects in developing high school students' research competency and attitudes. The chemistry-based research projects were carried out as a part of an informal program, in real-world laboratories on 330 high school…

High-voltage plasma arcs from solid-state Tesla coils were used to produce characteristic atomic emissions of various metals. The colored arcs produced were highly visible and vibrant, making for a spectacularly engaging demonstration for groups of varying sizes. The demonstration used an inexpensive solid-state Tesla coil to generate low-current,…

Raman scattering is a powerful tool for revealing the vibrations of molecules, but as a nonlinear optical phenomenon, its signals can change via mechanisms like resonance enhancement that have no direct analogue in infrared spectroscopy. In this work, complementary measurements conducted on 4-nitrophenol and its conjugate base allow students to…

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…

Integrating chemical management into a comprehensive emergency operations plan (EOP), including through the creation of a Toxic Materials Annex and a Hazardous Materials Annex, helps improve a school district's or individual school's preparedness for a chemical-related incident. To ensure the annexes remain relevant and useful, districts and…

The term "histology" was coined a little over 200 years ago and the subject has always relied on microscopy as its defining technology. Microscopy was and still is an essential approach for the description of cellular components and their arrangements in living organisms. For more than a century and a half, histology or microanatomy has…

Measurement uncertainty is a key topic in the university physics laboratory curriculum. In this study, we investigate students' ability to draw conclusions from measurement data and reasoning about measurement uncertainty in inquiry labs. This investigation centres around a task where students conclude whether measurements from two experiments…

Parasitic infections are declining in Japan, resulting in fewer hours of parasitology instruction in medical laboratory science and medical schools. However, there are growing concerns that the parasite identification skills of medical laboratory technologists and the diagnostic skills of physicians may be compromised as a result. Effective…

This study contributes to the literature by shedding light on students' learning by examining and comparing students' gestures in two educational contexts: geological field trips and classroom-based modeling activities. This study engaged 10 middle-school students in two different geological field trips and two classroom-based modeling activities…
