States of Aggregation
Solid, Liquid, Gaseous
It is winter. Snow and ice transform the landscape into a fairy tale scenery. At sub-zero temperatures, ice crystals form on branches and other objects. The snow cover is not always uniform but sometimes shows varied structures of snow and ice crystals as well. Snow is frozen rain, that is, precipitation falling from the clouds. Clouds, in turn, consist of gaseous water vapour which transforms into precipitation in certain conditions. Where the sun shines and temperatures rise again, snow and ice begin to melt. Thaw sets in, and snow and ice change into water again. But snow and ice can also exist simultaneously. Even at high minus temperatures, streams and rivers still carry water. On their banks, exciting ice formations can develop as a result. Stagnant waters, such as lakes and ponds, however, tend to freeze because the water in them hardly moves. The solid, liquid and gaseous states are the three classic aggregate states. We encounter the interplay between water vapour, liquid water and ice in many situations. Complex physical processes lie behind it. Let us take a closer look at them now.

Copyright
Copyright is subject to constant change to keep up with technological advances. This film enables the viewer to grasp the basic principles of this extremely intricate matter. By way of introduction, the film defines what an author is, what kinds of works there are and how long a work is protected on principle. Then the fundamental rights of an author are cited and it is shown how these are exploited in our times. In the third chapter, the respective rights are illustrated by way of practice-oriented examples of books, photos, music and films. Here, of course, an emphasis is laid on the field of education, taking into account the latest case law within the EU and Austria in particular. A further chapter highlights the problems arising with the Internet and goes into the citation law and pirate copies. All in all, in this way the viewer is made familiar with the most important basic terms and their meanings. Comprehensive worksheets and additional accompanying material invite us to deepen our knowledge of the subject.
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.
Ceramic
Ceramics are indispensable in our everyday lives. We eat from ceramic plates, drink from ceramic cups, use tiled ceramic bathrooms. But how is ceramic manufactured? The film reveals the secrets of this fascinating material! We get to know more about the beginnings of ceramic in the Old World of Egypt and Mesopotamia, about Greece, China and Rome. We gain interesting insights into the valuable earthenware and are also shown the exquisite further development of the "white gold". Today this versatile material is irreplaceable in industry, too. Whether in space or as an easily compatible substitute in medicine, ceramic is applied in many places.
