PPT-Essential idea: The constant need for new energy sources implies decisions that may have

Topic 8 Energy production 81 Energy sources Nature of science Risks and problemsolving Since early times mankind understood the vital role of harnessing energy and largescale production of electricity has impacted all levels of society Processes where energy is transformed require holistic approaches that involve many areas of knowledge Research and development of alternative energy sources has lacked support in some countries for economic and political reasons Scientists however have continued to collaborate and share new technologies that can reduce our dependence on nonrenewable energy sources.

To explain the functions and sources of carbohydrate, protein and fat.. To explain the functions and sources of different vitamins and minerals.. Nutrition. Structure of carbohydrate. All types of carbohydrate are compounds of carbon, hydrogen and oxygen. . Nature of science: . Theories: Many phenomena can be fundamentally understood through application of the theory of conservation of energy. Over time, scientists have utilized this theory both to explain natural phenomena and, more importantly, to predict the outcome of previously unknown interactions. The concept of energy has evolved as a result of recognition of the relationship between mass and energy.. Make strategic use of digital media (e.g., textual, graphical, audio, visual, and interactive elements) in presentations to enhance understanding of findings, reasoning, and evidence and to add interest. .
