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.
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.
Inclusion
Madita is eleven and blind. She does not want to go to a special school but to a regular grammar school. She says she feels "normal" there. Jonathan is eight and has a walking disability. He likes going to the school where he lives. Here, his best friend sits next to him. Max Dimpflmeier, a teacher who is severely deaf, explains that school life is not easy. Quote Max Dimpflmeier: "You don't want to attract attention, you want to avoid saying that it is necessary for you that 70 people adjust to your situation." People on their way to inclusion.
