Geiger-Müller Counter Tube
Radioactivity Measurement
Radioactivity leads to invisible radiation with considerable effects on the organism.
With the help of a Geiger-Müller counting tube, the decay processes of radioactive isotopes can be measured and converted into acoustic signals. The film presents the mode of action as well as the origin of radioactive radiation.
The bonus material shows experiments that can be used in physics lessons.

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.
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.
