Optics
Qualities of Light
This DVD offers a clearly structured overview of the field of optics with an emphasis on the following main topics: All three models, i.e. the ray theory, the wave theory and the quantum theory of light, are explained by means of selected phenomena. The pupils learn about the conditions, the principles and appearances regarding reflection and refraction and are encouraged to perform easy experiments themselves. Optics are introduced to the pupils with the help of examples from nature, road traffic and the environment. Simple optical instruments such as a magnifying glass, a camera, a microscope, an astronomic telescope and the eye are described. Further, the visible part of the electromagnetic spectrum, a line spectrum, a solar cell and a radiometer are explained in selected sections. The film is divided into six menu items (chapters), which may be individually accessed and worked on. For this purpose, additional pictures, texts or selected short film clips are offered, which can simply be called up by remote control.

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.
Rights and Obligations
Three girls of different ages: Anna is 17, Paula 15 and Lena 13. Before the law, their respective ages have consequences – because children and adolescents have different rights and also obligations.
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.
