Periodic Table
System of the Elements
With the help of the periodic system chemists can predict properties of chemical elements and derive chemical reactions. But you need not be a chemist to understand the periodic system. First of all the question arises: What is a chemical element? Chemists of the past noted here: “A chemical element is a chemical substance that cannot be further broken down into other substances.“ All known substances are formed by these elements. At present (2017) we know 118 elements. The elements 113, 115, 117 and 118 were added most recently in 2016. They belong to the so far 27 elements which cannot be found in nature but are man-made. Many of the remaining 91 elements are found only in the form of chemical compounds in nature, not in their pure form.

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.
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.
