Magnetism
The invisible force
You cannot smell, see, hear or feel magnetic force itself. So it seems quite magical to us when a metal object can be moved by a magnet through a glass plate as if by an invisible hand, or when we can stick a piece of paper to the refrigerator door with a small magnet.
Objects made of metal stick, float or are repelled by each other without us having a simple explanation of it.
But not only do many things we use in everyday life work with the help of magnetism, the Earth itself creates a magnetic field. So we are, on the one hand, surrounded by man-made magnetic objects, on the other hand, we live in a natural magnetic field produced by the Earth itself.

Stalking
n Germany, 12 % of all federal citizens are pursued by a stalker once in their lives. And not only celebrities are among their victims! Everyone may be confronted with such a situation.
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.
Internet Addiction
The film consists of two parts. The first part is the 15-minute short film “In the Net”. It describes the problem of excessive Internet use in a humorous way, in particular the risk of losing touch with reality when chatting. The second part illustrates with three real persons how Internet addiction can develop and the problems encountered by those who are afflicted. The authentic statements are commented by an experienced therapist. For many pupils, the issues addressed here are related to their everyday lives. What is a “sensible” use of the Internet, where does pathological addiction start? In contrast to addiction to alcohol, nicotine or drugs, the public seems to be largely ignorant of the problem of this addiction, which is not related to any substance abuse. The film provides material for discussion in the classroom (crossdisciplinary) and can be used as a basis for the formulation of prevention strategies.
