Halogens
The compounds of halogens are - with the exception of astatine - widespread, can be encountered in nature and are versatile substances. This fact is taken up on this DVD in order to teach the students the chemistry of the halogens by illustrating their special qualities and explaining the correlation of their structure with their chemical properties. In the first part, an overview of the element group of halogens lays emphasis on the common as well as on the distinguishing characteristics of fluorine, chlorine, bromine and iodine. In a second part, the specific properties of bromine and iodine are presented. This topic is linked to the students‘ everyday experience on the one hand (bromine as a catalyst for reactolite sunglasses, iodine as an agent in medicine, etc.) on the one hand. As a rule, they are of a kind that can only be realized with difficulty, or high expenditure in the chemistry classroom. With the help of these experiments, students are introduced to the chemistry of the halogens in a way that enables them to draw conclusions on the basis of their observations.

Der Friedensrichter von Neukölln
Hassan Allouche lebt in Berlin-Neukölln und ist das Gesetz – zumindest für viele muslimische Bewohner des Stadtteils. Der Film begleitet ihn, wie er als Friedensrichter von einem Konflikt zum nächsten eilt und z. B. dabei hilft, einen Familienstreit beizulegen. Er hat auch schon bei einem Fall von Schutzgelderpressung eingegriffen. Nur wenn es um schwere, meist körperliche Delikte geht, lehnt er jede Hilfe ab.

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.

Human Dignity
This is Albertine. She is seven years old. Three years ago, she lost her mother and has lived with her grandmother ever since, her father has left them. Every noon she comes to have lunch in the ward. The girl seems to feel her strength ebbing away and has decided not to talk anymore. The children at this stage believe that the grown-ups can prevent death but see that they're not doing so. Thus, they seal themselves off and retreat into their own world. And when this happens, Sister Marie Stella and her team prepare the children for death, just as they do with the grown-ups. Albertine was allowed to chose a dress from the dressmakers for the Christmas celebration.

Reptiles
This DVD offers a clearly structured overview over reptiles with an emphasis on the following aspects: The origin of reptiles is proven by fossil finds from all over the world. The skeletons are proof that reptiles were not confined to life on land but were also adapted to water and the air. The typical common characteristics of reptiles, such as the coat of scales and a poikilothermic body temperature, as well as the extremely different appearances of poisonous snakes and constrictors, turtles, lizards and crocodiles are discussed in detail. The different methods of finding food both as a herbivore or as an ambush predator with the use of poison or with the help of a pit organ are shown. The “invention” of the amnion made the reptiles’ reproduction independent from water and enab- led them to lay their eggs on land.
