The media package provides an introduction to the topic of renewable energies, which has also now become a highly topical item on the school instruction. The focus is on physics, geography and chemistry. The package answers the following questions: What does renewable mean? Why do we need renewable energies? What is the cause of the greenhouse effect? What renewable energy sources are available? Why is the sun a practically inexhaustible source of energy? Several media files (graphics, charts, photos, animations, interactive worksheets, experimentation instructions, information sheets, link lists and guidelines) will allow you to add a practical, real-world-oriented topic to your class!
