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…

The preservation of natural water and electricity resources is essential for the development of smart cities. Indeed, water and electricity are highly dependent and must be analyzed together to improve the energy efficiency. This article is about the study of the integration of renewable energy and smart solutions in a water heating system. The…

The aim of this study was to design a digital game that imparts the concept of urban heat island effects to aid in environmental education. Within the play-time limits, gamers must be alert to signs of warning from the environment and keep the balance between economic growth and the temperature of the environment, so they can safely manage the…

Research has demonstrated that many students and some teachers do not consistently apply the conservation of energy principle when analyzing mechanical scenarios. In observing elementary and secondary teachers engaged in learning activities that require tracking and conserving energy, we find that challenges to energy conservation often arise in…

The scientific method is arguably the most reliable way to understand the physical world, yet this aspect of science is rarely addressed in introductory science courses. Students typically learn about the theory in its final, refined form, and seldom experience the experiment-to-theory cycle that goes into producing the theory. One exception to…

Consumers are constantly being presented with choices that have economic, environmental, and lifestyle/social dimensions. For example, is an energy-efficient hybrid car (with regenerative braking) a better choice than a regular petroleum-only vehicle when considered from all three dimensions? Surprisingly, although each and all of these dimensions…

The article investigates the feasibility of district heating in a small town adjacent to a Kraft pulp mill in eastern Canada. A detailed heat demand analysis is performed for all buildings using a geographical information system and archived data provided by the municipality. The study shows that the entire space heating requirement of the town…

In presenting the basics of solar heating and hot water systems, this publication is organized from the general to the specific. It begins by presenting functional and operational descriptions of solar heating and domestic hot water systems, outlining the basic concepts and terminology. This is followed by a description of solar energy utilization…

A checklist of energy consumption reduction measures for universities is provided with the intent of achieving rapid and significant energy savings at minimal cost. Measures described should be within the scope of accomplishment by regular university operating and maintenance personnel. The measures involve non-technical actions such as adjusting…

In this project, we suggest building a real model of solar village inside schools, which use only solar energy. Such projects emphasize the importance of energy for a technological society and the advantage of alternative energy sources. In this study, we report on pupils in the 6th grade in three elementary schools in Israel who were active…
