Units of Length
Measuring and Calculating
The DVD starts with a look back into the past. How did peop- le measure in former times? What historical units of measure- ment were there? What is the standard metre? Since when has there been a system of units? Subsequently, the units of measurement – metre (m), centimetre (cm), milllimetre (mm), decimetre (dm) and kilo- metre (km) – are examined more closely. In a third chapter, an overview of the conversions is presented and their systematics explained. Decimal points and the prefixes are clearly illustrated. Then the DVD offers a digression visiting other countries and their length units. America and Great Britain, with inches, feet, yards and miles, play a central role. In the fifth chapter, calculations using scales are presented. Here the focus is laid on scales in maps, but also scaling down and up are dealt with. In the last chapter, circumferences of rectangles and squares are measured and calculated with various examples.

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.
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.
