We use new survey data from 1,203 households in rural Eastern India to estimate cross-sectional models of overall energy use and embedded emissions. Findings indicate that the primary driver of household energy use is household size and affluence. This is unsurprising and consistent with findings from the engineering literature on energy demand.…

What if you could challenge your fourth graders to create a minimally invasive, highly efficient dam? With this volume in the "STEM Road Map Curriculum Series," you can! "Hydropower Efficiency" outlines a journey that will steer your students toward authentic problem solving while grounding them in integrated STEM disciplines.…

Measuring innovation is key to realizing innovation in practice. One of the primary reasons why measurement is important stems from the fundamental principle that what is measured is, in turn, what garners attention and action. Systematic measurement of innovation can enable researchers and practitioners to propose and undertake strategic…

Metal-air battery technology is a promising new energy storage solution in the green energy economy but also an excellent tool to educate students on the working principles of batteries. A simple yet powerful construction of a metal-air battery is shown, which consists of a plastic mint box, a cathode, an anode, and an electrolyte. Furthermore,…

Energy conversion devices such as fuel cells, metal-air batteries, and electrolyzers have been envisaged as possible solutions for cutting down the continuous accumulation of greenhouse gases resulting from the combustion of fossil fuel. The bottleneck reaction for these devices is the oxygen reduction reaction (ORR) occurring at the cathode. The…

In this study, which focuses on selecting the material and predicting its mechanical behaviors in materials science, an Artificial Neural Network (ANN) was used to predict and simulate the low-speed impact effects of hybrid nano-doped aramid composites. There are not enough studies about open education practices in this field. Since error values…

Renewable energy is a global concern and should be incorporated into education to raise awareness among younger generations, including in physics education. Educators have made various efforts to raise awareness of the importance of pursuing renewable energy. A breakthrough sought in this research is to incorporate collaborative learning into the…

In this research, an educational approach to the concept of energy is proposed. It is based on the history of physics. In 1854 Hermann Hemlholtz gave a popular lecture on the recent discovery that energy is conserved. Such lecture is used as a guide to introduce the pupils within several nuances of this concept. Not much mathematics is used, so…

Green internet of things is important to achieve atmospheric decarbonisation, it is crucial to implement procedures and practices that prioritise resource conservation and environmental protection. However, the growing use of internet of things devices poses a challenge due to their high-energy requirements for data reception and transmission…

The research aimed to describe the development of solar electric cars as a prop in energy conversion learning using the analyze, design, develop, implement, and evaluate (ADDIE) model and to ascertain the effectiveness of an electric car as a prop in energy conversion learning. Utilization of prop in the learning process is one way to support the…

The concepts of electronegativity and classical electronegativity scales are briefly described. Electronegativity scales have practical quantitative applications, and this work suggests activities which can assist students select the scales for use in chemistry applications. It provided examples of the use of an appropriate electronegativity…

The Edison Institute predicts that there will be at least 19 × 10[superscript 6] all-electric vehicles (EVs) in use by 2030. This will produce significant effects on our transportation system and its energy requirements. Investigating these effects is an ideal activity to show the relevance of physics. How efficient are EVs in using energy? What…

There is general consensus within students and staff in higher education that designers have to be 'eco-conscious', making decisions every day that will consciously or non-consciously impact their carbon footprint in multiple ways, from the files they are saving, to the designs they are creating. However, in further/higher education, it is still…

Eigentheory concepts are central in mathematics and physics; they serve multiple functions, such as symbolizing physical phenomena and facilitating mathematical computations. Words and meanings associated with eigentheory develop and vary over time, as do their associated symbols. In this study, we investigate how "eigen" develops over…

Fostering students' critical thinking skills is an urgent issue that requires immediate attention. One viable solution to address this is the implementation of project-oriented problem-based learning (POPBL) through the SR-STEM project. This research aims to describe the implementation, effectiveness, and student perception of the POPBL model…
