Solutions, Emulsions and Mixtures of Substances
Properties and Uses
Be it milk in a cereal bowl, tea in a glass or the air around us. We constantly come across mixtures of substances in our everyday lives. As the name suggests, they are mixtures – mixtures of several so-called pure substances. They are, for instance, the chemical elements listed in the periodic table. These are substances that only consist of one single element, for example sulphur. But there are also pure chemical compounds such as distilled water or sodium. If you solve sodium or other substances in regular water, the result is a mixture of substances. A mixture is formed from different chemical compounds. With mixtures of substances like this, the source substances remain in the mixture as individual units – even if you cannot distinguish them with the naked eye. Nevertheless, they can be divided into their individual components with the help of various separation methods.

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.
Pupils Practise Inclusion
When people come together, no matter under what concomitant circumstances – ultimately, it is about how these people meet and how openly they interact with one another.
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.
