This work presents a sequence to introduce resistive gas sensors in the classroom. It explains the physical principle of the metal oxide semiconductor sensors and exemplifies its real interfacing through the sensor model MQ-2. Besides, it also presents the design of two electronic systems to indicate the level of alcohol concentration in the air,…

In a technology-centric world, leveraging digital tools such as chatbots allows educators to engage students in ways that may be more accessible for both parties, particularly in large lecture classrooms. This report details the development of an interactive web-based chatbot to curate content for writing about chemistry in context. Students were…

An important objective of any analytical chemistry course is for students to generate and interpret data from the analysis of complex, real-world samples in order to assess the effectiveness of the analysis method, including the calibration. In this laboratory exercise, students directly compare calibration methods (external standards and standard…

Many students may not be aware that renewable biological materials can be converted into multiple bioproducts and biofuels using a biorefinery process, a more sustainable alternative to conventional crude oil refineries. By using waste from pineapple, a plant material that most students are familiar with, a biorefinery can be modeled to…

Three real-world datasets are introduced for a petroleum engineering capstone design course, providing detailed problem statements, assessment criteria, team-building practices, and required software packages. Two surveys reveal that students prefer real datasets over synthetic ones, and despite initial challenges, students feel proud of their…

From a tradition of fieldwork-based teaching in geography, we consider the intersections of fieldwork sites and their social and spatial relationships for implications for non-placement work integrated learning (NPWIL). As the skills agenda gathers pace in universities it is critical to understand forms of NPWIL and their development. As a form of…

Thermal conductivity is generally the tool of choice for quantification of fixed gases, particularly lighter-than-air gases. Unfortunately, gas chromatography-thermal conductivity detectors (GC-TCDs) are difficult to introduce in first- and second-year chemistry courses where the cost and number of instruments, as well as the space required, is…

Biodiesel is an important biomass, largely employed in the transport sector and produced from vegetable oils. Additionally, waste cooking oils may be reused to produce biodiesel fuel, minimizing environmental pollution. A laboratory experiment that affords a widespread way to discuss degradation concepts and tools for used vegetable oil…

Fossil fuel corporations play a significant role in promoting their interests in schools and other educational institutions, a practice that has recently been labelled as 'petro-pedagogy.' But this role goes beyond the production of the pro-petroleum and anti-science corporate propaganda that tends to attract the most critical attention. In this…

A large proportion of people in western societies do not believe in the concept of human-induced climate change (HICC), and oil-dependent economies might be expected to have more climate contrarian populations than others. Recent recessions in the Norwegian oil industry caused an influx of dismissed oil engineers into Norwegian science teacher…

The aim of this study is to determine the views of candidate science teachers about environmental problems and solutions to these problems. One of the qualitative research designs, phenomenology, was used in the research. Data were collected with a semi-structured interview form developed by the researcher. In the analysis of the research, a…

This 45 minute inquiry lesson can be used for a high school world geography or AP Human Geography course when the class discusses various issues regarding world energy resources. The lesson focuses on two particular issues: fossil fuel dependency and the growing energy demand. Students will examine the geographic distribution of current energy…

This article aims to introduce the actinides and some aspects of nuclear chemistry to teachers and their students. The actinides are a group of f-block elements with atomic numbers from 90 to 103. (The term 'actinoids' encompasses both the actinides and actinium itself). All of the actinides are radioactive but they also have a rich inorganic…

Laura A. Schifter and Jonathan Klein highlight the many ways in which K-12 schools and students have tremendous potential to advance solutions on environmental issues, and they provide frameworks for enacting change, in "Students, Schools, and Our Climate Moment." Schifter and Klein demonstrate how the effects of climate change intersect…

Technology and validation methods for producing biodiesel have been updated and have kept advancing. Creative raw materials used in producing environmentally friendly biodiesels have also attracted interest from scientists. Thus, learning and teaching methods on biodiesel production at the high school level need to be up to date. However, there…
