Optics
Qualities of Light
This DVD offers a clearly structured overview of the field of optics with an emphasis on the following main topics: All three models, i.e. the ray theory, the wave theory and the quantum theory of light, are explained by means of selected phenomena. The pupils learn about the conditions, the principles and appearances regarding reflection and refraction and are encouraged to perform easy experiments themselves. Optics are introduced to the pupils with the help of examples from nature, road traffic and the environment. Simple optical instruments such as a magnifying glass, a camera, a microscope, an astronomic telescope and the eye are described. Further, the visible part of the electromagnetic spectrum, a line spectrum, a solar cell and a radiometer are explained in selected sections. The film is divided into six menu items (chapters), which may be individually accessed and worked on. For this purpose, additional pictures, texts or selected short film clips are offered, which can simply be called up by remote control.

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.
