Quinacridone red and violet are visually different colors, an observation confirmed by their visible reflectance spectra and CIE L*a*b* coordinates. However, their IR spectra are extremely similar. Though chemically identical, the two quinacridones are polymorphs. In this experiment, designed for and tested by nonscience majors, the pigments are…

Although most students in nonmajor biology courses will not enter careers in science, they will need a working understanding of biology and how it relates to their lives to make informed decisions on important topics that will affect their lives, including food, environment, energy, and health. This research seeks to improve on nonmajors'…

Buckminsterfullerene (C[subscript 60]), along with diamond and graphite, appears in many chemistry textbooks as an example of an allotrope of carbon. This communication describes a hands-on activity to explore the characteristic structure of C[subscript 60] through the construction of a structural model using transistors and plastic tubes…

Over the years it has become more common for practitioners to use the NGSS scientific practices to inform curricula at the undergraduate level. One of these practices is argumentation, the process of engaging in argument from evidence. Argumentation is an important part of the scientific process because scientists must make claims about their…

Understanding organic reaction mechanisms can be a challenging task for many undergraduate students, particularly those who are nonchemistry majors, despite the fact that organic chemistry is a mandatory course for numerous science and engineering undergraduate programs. The selectivity of a reaction is largely determined by the distribution and…

Like many other universities, Musical Acoustics is offered at our school as a lab-based course fulfilling general science requirements for non-majors. The course has been team-taught by a physics professor and music professor since its earliest inception and, by far, the most popular unit explores room acoustics through a variety of activities and…

Kombucha, a popular probiotic beverage, contains detectable concentrations of ethyl alcohol. To be sold as a nonalcoholic product, alcohol concentrations in kombucha must be shown to be less than 0.5% by volume. This paper describes the use of an inexpensive, commercially available sensor to reliably and accurately measure alcohol concentrations…

Colleges throughout the United States typically expect their students to take at least one course in the sciences to fulfill liberal studies curriculum requirements. For nonscience majors, the choice of science class can include introductory chemistry, introductory biology, and astronomy, among others. Based upon interactions both in and out of…

Traditional lab courses separate lectures from lab work, whereas integrated lab-lecture courses (also known as studio courses) combine both in a single session under one instructor. Previous studies suggest that integrated lab-lecture courses may have the potential to enhance the learning experience for introductory-level students. In this…

Purpose: The purpose of this study was to develop the augmented reality (AR) educational program combined with the instructional guidance for supportive learning, which enhanced the thinking process cooperative discussion and problem-solving skills in chemistry subject. Design/methodology/approach: The method used the quasi-experimental research…

We designed an interdisciplinary project-based learning course in hydroponics for undergraduate non-science major students. Students worked in teams to design, build, and maintain plants in various types of hydroponic systems over the semester. In three semesters of teaching the course, students consistently demonstrated knowledge of course…

The two-semester General Chemistry laboratory sequence for nonchemistry majors at James Madison University has recently made the transition from expository, confirmation experiments to project-based (first semester) and research-based (second semester) curricula; this narrative will describe the development and current state of the Brewing Science…

A 3-year study (2017-2019) was conducted to obtain the views of nonmajor undergraduate students about discussions in learning physiology. The teaching methods used were lecture only (lecture), group discussion alone (discussion), and a combination of lecture and discussion (lecture + discussion). Students were assigned homework in a textbook, and…

This paper reports a demonstration of a 90 min on-demand class where a chemical experiment is performed to educate nonscience majors on surfactants. First-year undergraduate students perform the water ball in a water bottle experiment at home and learn about the structure and properties of organic compounds in the demonstration. The experiment is…

An innovative food laboratory for a chemistry of food and cooking course has been developed for nonscience majors and under-represented students in science. To help these students succeed in science, a laboratory was designed to engage students using food and cooking as a medium for building a stronger foundation in chemistry. Each food laboratory…
