"Ulysses" by James Joyce (1882-1941) has a surprising amount of 19th-century, classical physics. The physics community is familiar with the name James Joyce mainly through the word "quark" (onomatopoeic for the sound of a duck or seagull), which Murray Gell-Mann (1929-2019 -- Physics Nobel Prize 1969) sourced from Joyce's…

Determination of enzyme activity is crucial for discovery, research, and development in life sciences. The activity of enzymes is routinely determined using spectrophotometric assays that measure rates of substrate consumption or product formation. Though colorimetric-based detection systems are simple, rapid, and economical to perform, the…

We have developed new rotors that can be classified into three groups by changing the rotors used in simple motors into various types. Group I has a semicircular shape rather than a perfect circle or square shape, group II has a structure consisting of several closed circles on one plane, and group III has a three-dimensional shape. We wanted to…

The novelty of the COVID-19 disease has paved the way to numerous scientific studies that aim to further understand its biology, and to different strategies that disseminate this information to promote public awareness. One of the strategies that the academe can employ is the inclusion of COVID-19 as a topic in a basic biotechnology course. This…

The trajectory of a ball rolling across an inclined plane was recorded on video film to determine if it followed a parabolic path as others have suggested. The challenges in this case were (a) to determine the magnitude and direction of the friction force on the ball, (b) to determine the effect of the friction force on the trajectory and (c) to…

A comprehensive laboratory work that allows students to gain hands-on skills in energy-efficient mechanochemistry is described. Standard university curricula are paying very little attention to mechanochemistry, although skills in this discipline are highly demanded among chemistry graduates. In this study, a comprehensive description of…

While visual representations are generally thought to help students learn chemistry, they can pose conceptual challenges. Arrows are a common visual feature used prominently across various visuals, such as energy diagrams. Although energy diagrams are widely used, research on what challenges arise in the context of energy diagrams is limited. To…

Blue (B), yellow (Y), red (R), and green (G) color-changing dye was used in a general chemistry course for first-year undergraduate students with nonscience majors to highlight the redox reactions written as the gain and loss of hydrogen. The first experiment is a vibrant color variation using a synthetic dye of indigo carmine. The second…

Citizen science is recognized as an important tool to engage the public in important scientific and environmental issues that impact them. Mosquito surveillance-based citizen science in college curricula have not received much attention even though its usage has the potential to actively engage students in inquiry and elevate student support for…

The alignment of teaching and assessment in chemistry courses is critical for the practice of science and positive student learning outcomes. This paper addresses how instructors can align what they do in class with assessments across topics to improve students' understanding and explanations of chemical phenomena. We drew on the foundations of…

Writing is usually integrated in the curriculum of science studies. However, students often lack the skills to write for various audiences or, to produce a well written manuscript. We developed a concise project of 15 European Credits to improve the writing skills in an early phase of the bachelor study. Students worked on texts from various…

The purpose of this study was to investigate undergraduate students' conceptions of Earth scientists, using drawing as a tool, during introductory Earth science courses. We explored two research questions: 1) What student conceptions are evident in undergraduate students' drawings of Earth scientists? and 2) How do undergraduate students'…

Literature on student ideas about circuits largely focuses on misunderstandings and difficulties, with seminal papers framing student thinking as stable, difficult to change, and connected to incorrect ontological categorizations of current as a thing rather than a process. In this paper, we analyzed 417 student responses to a conceptual question…

Field studies are defined here as any study of the natural world that occurs beyond classrooms. There is rising concern for the future of field studies in Earth and Environmental Sciences in Higher Education, despite being core to environmental inquiry, as cost-cutting across the sector was intensified by the COVID-19 pandemic. This paper reviews…

The field of science education has long advocated for students to leave K-12 education with an appreciation for the diversity of research methods scientists employ in order to effectively engage with research generated across many scientific fields of study. Yet, research has indicated that students typically believe research proceeds according to…
