Mushrooms
An Unknown Realm
This DVD offers a clearly structured survey of mushrooms with an emphasis on the following aspects: Mushrooms of different shapes and colours present their fruit bodies. The reproduction by means of spores is shown with different kinds of mushrooms. The actual mushroom is formed by hyphae in the ground. The symbiosis between mushroom and tree is called mycorrhiza. Mushrooms can be poisons or medicines, as is illustrated by the examples of ergot and the birch polypore. Mildews and slime moulds are examples of the decomposing effects of mushrooms. In the fermentation of yeast plants, sugar is transformed into alcohol and carbon dioxide. Lichens are extremely adaptable. Under the electron-scan microscope, we can see how algae and mushroom hyphae form a complex symbiosis. Finally, rules and recommendations for gathering mushrooms are provided. Outstanding shots (with impressive fast-motion pictures and animations) give the pupils a comprehensive overview of the characteristics of mushrooms.

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.
