Kathetensatz des Euklid
Flächensätze III
Das Quadrat einer Kathete ist genauso groß wie das Produkt der Hypotenuse mit dem zugehörigen Hypotenusenabschnitt. Diesen Lehrsatz formulierte und bewies Euklid von Alexandria. Mit diesem Wissen lässt sich etwa die erforderliche Länge eines Dachbalkens berechnen oder auch die Länge von Befestigungsseilen an einem Sendemast. Der Film leitet zunächst den Kathetensatz her und stellt die Beweisführung anschaulich dar. In einem zweiten Teil wird sodann das erworbene Wissen in unterhaltsam animierten Aufgaben angewandt und vertieft. In Verbindung mit dem Zusatzmaterial (klassische und interaktive Arbeitsblätter, Glossar, kommentierte Linkliste) lässt sich die DVD hervorragend im Unterricht einsetzen.

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.
Rights and Obligations
Three girls of different ages: Anna is 17, Paula 15 and Lena 13. Before the law, their respective ages have consequences – because children and adolescents have different rights and also obligations.
Computer Games
This film covers the topic of computer games in a variety of ways and from many different angles. Apart from the fascina- tion of computer games for users, the historical development as well as the production of computer games are described. The established genres are introduced, the guidelines of the German BPjM are explained. In light of recent public discussions, a neutral overview of the pros and cons of playing computer games is given, and different kinds of player behaviour are outlined. In this film, the pupils will recognise many aspects of their favourite pastime that encourage an independent, constructive use of this medium and reinforce their media competency. The film and teaching material are very closely related to the real-life situation.
