Fish
Vertebrates 1
This DVD offers a clearly structured overview of fish with an emphasis on the following aspects: The typical body build of fish and their adaptation to the water habitat are shown. The fish skeleton proves that they are vertebrates. Their sense organs (eyes, nose, barbels, lateral lines) are adjusted for survival in water. The skin is characterised by different kinds of scales. Free water fish, ground fish and surface fish are distinguished from each other by three typical mouth and body shapes. Locomotion in the water is made possible by different kinds of fins. Respiration through gills is a typical feature of fish. Herbivores possess typical characteristics distinguishing them from carnivores. Swarm fish and loners display different behaviour patterns. The film is divided into six menu items (chapters), which may be individually accessed and worked on. For this purpose, additional pictures, diagrams, texts or selected short film clips are offered, which can simply be called up by remote control.

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.
Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
