Kosinus
Flächensätze V
Der Kosinus ist das Verhältnis der Länge der Ankathete zur Hypotenuse.
Er ist gleichzeitig die Erweiterung des Satzes des Pythagoras um den Korrekturterm – 2 * b* c* cos α, also a2=b2+c2- 2 * b* c* cos α.
Damit können Kräfteverhältnisse ebenso wie Entfernungen zweier sich auseinander bewegender Gegenstände errechnet und dargestellt werden.
Der Film schließt die Reihe der Mathematikfilme zu den Flächensätzen ab und folgt dabei dem bewährten Aufbau seiner vier Vorgänger: In einem ersten Teil wird der Kosinussatz in zahlreichen unterhaltsamen Grafiken und Animationen hergeleitet, der zweite Teil vertieft und erweitert das Wissen in animierten Aufgaben, die in ihrer Komplexität ansteigend angeordnet sind.
In Verbindung mit dem umfangreichen Zusatzmaterial (klassische und interaktive Arbeitsblätter, Testfragen, Glossar) lässt sich die vorliegende DVD hervorragend im Unterricht einsetzen.

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.
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.
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.
