From Stone to Glass
Where Does Our Glass Come From?
In terms understandable to children, this DVD illustrates how glass, a widely used material, is made. The film shows, step by step, the development from rock to quartz sand, which, mixed with further ingredients, forms an important component in the making of glass. In order to give the children an exact idea of glass production, a glassblower is watched at his job. The accompanying material contains extensive suggestions and recommendations, such as songs, experiments, tips for assembly, games, mandalas, etc., both for a practical application of the topic in the classroom and for reinforcing the knowledge the children have acquired. Special emphasis was laid on an integrated learning experience in kindergarten life for the children to experience the often used material glass with all their senses. Thus, this DVD offers a basis suitable for child-oriented projects in kindergarten and early primary school, which take up and illustrate a topic familiar from the children’s everyday lives.

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.
Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
