Concerns regarding students' difficulties with the concept of energy date back to the 1970s. They become particularly apparent for systems involving adenosine triphosphate (ATP), which plays a central role in maintaining the nonequilibrium state of biological systems and in driving energetically unfavorable processes. One of the most…

In recent years, single-subject experimental courses have not been able to meet the demands of the comprehensive development of life sciences. This study is based on two fundamental disciplines, molecular biology and metabolomics, with the analysis and intervention of tumor-related genes as the starting point. A comprehensive experimental course…

Simple mathematical models can serve to reveal the essence of experimental phenomena and scientific concepts. The particle in a box (PIB), for example, is widely used in undergraduate programs to teach the quantum mechanical principles behind the UV--vis spectra of conjugated polyenes and polyynes. In this work, the particle on a ring (POR) and…

The educational benefit of the traditional didactic lecture to learners in Higher Education is hotly debated. Given increasing student numbers, existing technical set ups and many logistical concerns, lectures remain the norm in many Higher Education Institutions (HEIs). In this personal view piece, we discuss the benefits, opportunities, and…

The use of approximations in solving problems in sciences can be vital for students. Order of magnitude estimation also helps with physical understanding of the quantities involved in a calculation. For example, in the first exam in a first-year class in chemistry the student must find the mass in grams of an atom; a couple of students will…

High-performance liquid chromatography is one of the primary techniques covered in the undergraduate analytical chemistry curriculum. This technology report describes the use of a portable capillary-scale instrument that can provide similar performance to a benchtop instrument but generates less solvent waste and enables operation in nonlaboratory…

Undergraduate organic chemistry students, as they study conformational analysis and stereochemistry, frequently have trouble manipulating three-dimensional structures on a two-dimensional page or screen. The inability to accurately convert three-dimensional bond-line representations into Fischer projections is one example of this. While some…

This article describes a simple way to introduce nanomaterials using the presence of carbon nanodots (CNDs) in widely available food. Budweiser® beer and Coca-Cola®, commercial foods that are commonly accessible, were utilized to demonstrate the optical property of nanoparticles. Specifically, green and violet laser pointers were employed for the…

The process of method development is at the heart of analytical chemistry, yet direct experimental experience with the process is rarely taught in the undergraduate laboratory. We report here an experiment that uses rapid, safe, and inexpensive paper-based microfluidics with cell phone detection in order to facilitate the development of a…

Many recent studies document the difficulties that students experience when learning organic chemistry, often due to the complex visualization and reasoning skills required to successfully understand the ways molecules interact in specific environments. Many of these studies call on instructors to improve their teaching strategies to support…

This review presents an overview and analysis of the body of research on special relativity theory (SRT) education at the secondary and lower undergraduate level. There is currently a growing international interest in implementing SRT in pre-university education as an introduction to modern physics. For this reason, insights into learning…

Students are introduced to the concepts of static electricity at a school level and an under-graduate level. In this paper, we present an inexpensive and portable device that can be used to study the static electricity and verify polarity of the electric charge on materials in a triboelectric series. This device is developed at the Science…

This report details the design of an online trilingual (English, French, and Portuguese) interactive virtual board game and its implementation at the Federal University of Ceará in Brazil. It was used as a fun alternative to assist chemistry and pharmacy undergraduate students in reviewing introductory concepts to organic reactions: enthalpy,…

In our technology driven world today, it is extremely important to increase the science literacy of our non-science majors. At Stockton University, this goal is attempted to be accomplished through our General Studies courses. This paper describes a lab-based course in the General Studies curriculum, 'The Science of Ice Cream'. At Stockton…

Herein we present an engaging description of the existent analogy between social distancing during the COVID-19 pandemic and the collision cross-section of particles as defined in the collisional model for a chemical reaction. In addition, the link between collision cross-sections and kinetic rate constants is thoroughly established, bridging…
