X-Radiation
Discovery, Properties and Applications
They are enormously rich in energy and easily penetrate the body but in spite of this, we can neither see nor feel them: X-rays work in secret. Because of their physical properties we owe important advances in medicine to them. Their ability to see through the body and make bone and tissue structures visible allows us to diagnose fractures or diseases without opening the body. X-rays, artificially generated in an X-ray tube, are ionising like radioactive radiation and can impair the functions of body cells. Therefore, the use of X-rays is subject to strict regulations because benefits and possible harmful effects, above all of X-ray examinations and radiotherapy, must be carefully weighed up.

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.
Ceramic
Ceramics are indispensable in our everyday lives. We eat from ceramic plates, drink from ceramic cups, use tiled ceramic bathrooms. But how is ceramic manufactured? The film reveals the secrets of this fascinating material! We get to know more about the beginnings of ceramic in the Old World of Egypt and Mesopotamia, about Greece, China and Rome. We gain interesting insights into the valuable earthenware and are also shown the exquisite further development of the "white gold". Today this versatile material is irreplaceable in industry, too. Whether in space or as an easily compatible substitute in medicine, ceramic is applied in many places.
