Report on energy-environment education in physics class

The purpose of the teaching of environmental problems is that the students who live in the 21st century acquire a moral and practical understanding of these issues. In a class of the high-school physics, energy and environmental problems were taught. They learned the second law of thermodynamics and the irreversibility principle in physics, and the energy-environmental problem. As a practical assignment, they surveyed saving methods of electric energy in their home, and reduced its consumption. Students' impressions of this assignment are also introduced. (author)
