Amphibians
Vertebrates 2
More than 350 million years ago, the evolution of amphibians set in. Amphibians developed from fish – a first step towards life on land. Diverse reproduction strategies, manifold forms of appearance and a broad spectrum of sizes, ranging from the tiny Brazil litter frog to the giant salamander, constitute the special characteristics of the class of amphibians. The pupils learn about the different respiration techniques and the particularities of the amphibians’ circulatory system as well as about their defining characteristics and their repro- duction strategies. Moreover, the threat to amphibian species posed by environ- mental poisons and the climate change is also discussed. This DVD leads the pupils into the fascinating, unknown world of amphibians, which still remains to be fully researched.

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.
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.
