Licht und Farbe
Lebenselexiere der Erde
Ohne Licht würde auf unserer Erde kaum Leben existieren. Pflanzen brauchen diese elektromagentischen Wellen, um zu wachsen und durch den Vorgang der Photosynthese unter anderem Sauerstoff zu produzieren. Genauso sind Farben wesentlicher Bestandteil in der Natur und haben ihre eigene Bedeutung. Auffällige Färbungen bei Reptilien sollen Gefahr signalisieren, während ein möglichst prächtiges Federkleid bei Vögeln ihre Attraktivität steigern soll. Genau wie andere Arten reagieren auch Menschen auf Licht und Farben. „Schau dich schlau!“ zeigt, wie die beiden Komponenten eingesetzt werden, um uns Wohlbehagen zu bescheren oder uns zum Beispiel zum Kaufen zu animieren. Joey Grit Winkler besucht ein Lichtlabor, wo sie genau erfährt, was Licht überhaupt ist, und man ihr erklärt, wieso beispielsweise die Sonne beim Untergehen rot wird. Außerdem findet Joey heraus, welchen Einfluss Licht auf unsere Stimmung hat und wie die mit bloßem Auge unsichtbaren Wellen für medizinische Zwecke eingesetzt werden. Aber genauso wie Licht heilen kann, so kann es auch krank machen. In „Schau dich schlau!“ erläutert Joey Grit Winkler alles Wissenswerte über Licht!

Blogging
The weblog or blog, for short, as a medium is not much older than this century. Blogs came into being in the World Wide Web as ’messages from below’, as web pages from web creators who wanted to share their view of the world with the world. They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.
The Daily Newspaper
Every day, there is a surge of news reaching us via different news channels. In spite of TV and Internet, the daily paper still is one of the most important main sources of news. But how is a newspaper created? The film shows the production of a paper in the course of one day. Starting with the editorial meeting in the morning, in which the topics and deadlines are determined, the film accompanies a journalist during her research work. You can see how a journalistic interview is conducted and what the photographer must consider when taking a press photo. Back in the editorial office, the editor’s work is illustrated, which includes the page layout and the writing of an online article in today’s time. Impressive pictures from the printing centre depict the process from the digital page to the finished newspaper. Together with the comprehensive accompanying material, the DVD is perfectly suited for use at school
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.
