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 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 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…

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…

The principles of process-oriented guided inquiry learning (POGIL) are applied to the analysis of the emission spectrum of atomic hydrogen. Over the course of three learning cycles, students construct the hydrogen atom's energy level diagram and assign quantum numbers using their measurements of the Balmer series plus additional information on the…

It is not only worth talking about the chances of survival in the fight against emerging environmental and socio-economic threats, but it is necessary to use all possible means to influence public awareness. It is awareness that shapes our attitudes and literacy. The core of these tools is cross-sectoral place-based education. This raises the…

It is now widely understood that societies must rapidly decarbonize to avoid the worst impacts of future climate change. To contribute to this urgent effort, academic libraries should develop an understanding of the carbon footprint resulting from their activities. This article shares the results of an effort at the Penn State University Libraries…

Modifications are presented for the iodine clock reaction to introduce the concept of activity and to help students better appreciate molecular aspects of chemical equilibrium. The addition of an unreactive salt affects the activity of the reactants in the iodine clock reaction. The difference in activity affects how long the iodine clock reaction…

In this article, we analyze images from the book "Our Friend the Atom," written by the astrophysicist Heinz Haber in 1957 and developed in the Disney Science Department. In addition to analyzing the work, we investigate its relevance for science education. After the US attack on two Japanese cities with atomic bombs, there was a…
