Solar Energy
Renewable Energies II
80 % of our current energy needs are covered by fossil fuels (coal, oil, gas). Their supply may soon lead to severe problems as worldwide stocks will be exhausted one day. That is why the future belongs to renewable energy from sun, wind, water, and biomass. The Sun as an inexhaustible energy source is estimated to be available to us for another 4.5 billion years to come. It supplies us with “clean energy“ that is available everywhere on earth and that exceeds worldwide energy needs many times over. The film presents the pupils with the long history of solar energy use. The functioning of solar collectors, solar cells and solar power plants is explained, the current operating ranges of solar technology are dealt with and an outlook for the future is provided. With the act on the phasing-out of nuclear energy Germany has taken over a pioneering role worldwide in the field of renewable energies. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.

Seal of approval
Quality seals such as the "Bio-Siegel", "Blauer Engel", "Stiftung Warentest" and up to 1,000 other seals represent characteristics such as sustainability, health or safety with regard to a product, a service or even a company.
Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
Youth Movement
Dancing until your feet hurt: Here, at the meeting on the Hoher Meissner near Kassel, 3,500 participants from Boy Scout associations, youth and Wandervogel groups from all over the German-speaking region have gathered. They want to celebrate, simply get to know each other and commemorate a historic anniversary.
