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.

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.
