Air and Respiration
Learning Circle
The subject of air and respiration offers a variety of starting points for an interdisciplinary approach. This DVD contains essential aspects for teaching pupils in the first years of secondary school. The chemical and physical characteristics of air form the basis for understanding many everyday phenomena, ranging from the development of wind and air pressure to high pressure and low pressure areas in the atmosphere. Last but not least, the foundations for a closer examination of respira- tion are laid. The fundamental phenomenon of respiration is shown from a functional point of view with the help of impressive ani- mations. Different respiratory organs are compared to each other and the basic principle of respiration is explained. The respiratory movements, the path of respiratory air and gas exchange are main points in the “Respiration with Humans” chapter. As a special feature, in its ROM part this DVD offers material for a learning circle dedicated to this subject. Here, many aspects are treated again in a way that pupils can find out facts by themselves with the help of suitable experiments and tasks.

“Tolerance means being generous and kind to other people and helping them, too.”
Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
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.
