Recently, smart sensing/actuation paper has attracted significant interest due to its potential usage as a sustainable component in future electronics, robotics, and intelligent sensing devices. In acknowledging the importance of this topic for the engagement of students at the university level in conjunction with Industrial Revolution 4.0, it is…

The relationship between surface area and dynamics of processes can be demonstrated by adding iron at room temperature to liquid nitrogen. The rate at which the liquid nitrogen boils to produce gas is related to the surface area of the iron. Adding iron in the form of consistent units that have measurable sizes can be readily connected to…

Calorimetry is a central concept in the first semester general chemistry curriculum, and constant pressure (coffee-cup) calorimetry is a common experiment in the laboratory. However, constant volume (bomb) calorimetry is traditionally reserved for the physical chemistry laboratory. This article describes the advantages of incorporating bomb…

A new undergraduate organic laboratory experiment has been developed and implemented for the Ugi three-component synthesis of the topical anesthetic lidocaine with excellent atom economy. Paraformaldehyde, diethylamine, and 2,6-dimethylphenyl isocyanide were combined and conveniently stirred at room temperature for a week in methanol with acetic…

In an effort to further develop critical thinking and problem solving skills, a guided-inquiry-based, multioutcome organic chemistry synthesis and characterization experiment was developed. Students were provided with the protocol for a time-saving microwave-assisted acetanilide synthesis reaction from acetic anhydride and an unknown primary aryl…

This paper introduces hands-on curricular modules integrated with research in atmospheric ice nucleation, which is an important phenomenon potentially influencing global climate change. The primary goal of this work is to promote meaningful laboratory exercises to enhance the competence of students in the fields of science, technology,…

Educational content is consistently adapted to enhance the learning experience of students at all experience and skill levels. Student motivation and accessibility are key factors in teaching science to a broad audience. The presented experiments engage the students by relating the content to that which is immediately relevant to them: the threat…

Green chemistry metrics and life-cycle analysis (LCA) were used to assess inefficiencies in two current organic chemistry experiments conducted in third-year organic chemistry to synthesize ("E")-stilbene from benzaldehyde. An alternative Wittig-based, greener, one-pot experiment using the same starting material was selected as a vehicle…

A laboratory experiment was designed and implemented in a STEM teaching laboratory at Michigan State University to engage students in an activity that not only introduced an innovative nitrate detection technique but also addressed one of the negative impacts of climate change, that is, the eutrophication of water bodies. The adverse effects of…

We have investigated the motion of water flow through glass tubes of different shapes by calculating the value of the Reynolds number denoted as Re. We know that at a given flow rate the value of Re determines the type of flow being classified as laminar, transitional or tubulent. The dependence of Re in different configurations of glass tubes as…

Nowadays, discussing global environmental issues has become regularly included in STEM-based higher education, emphasizing the importance of the youth in finding "ad hoc" solutions for the climate crisis. One of the most commonly applied strategies is promoting sustainable choices among students, especially linked to their lifestyle…

Providing exposure to the process and methods of science is a fundamental goal of any general education college science course. This is largely because most students taking such courses are generally "not" science majors, so they are likely to take few, if any, other science courses. Meeting this goal can be a challenge in courses such…

Although teaching of environmental physics and energy-related topics has increased in the last several years, only a small portion of that has been for non-science majors. Environmental physical science can be used to teach physics to non-science majors by applying learned physics concepts to current issues of interest such as climate change,…

This study aimed to examine the effect of four types of assessment on overall student success in an online college-level climate change course. Quizzes, midterms, lab assignments, and a capstone project as well as knowledge check questions were used to assess different aspects of student learning, consistent with Bloom's taxonomy hierarchy.…

An integrated and inquiry-based experiment on solid state chemistry is applied to an inorganic chemistry lab course to provide insight into the characteristics of the solid phase reaction. In this experiment, students have the opportunity to synthesize long-lasting phosphors with formula xSrO·yAl[subscript 2]O[subscript 3]:Eu[superscript 2+],…
