Poison
Throughout history, humans have always tried to understand the mysterious power of toxins. In doing so, they sometimes discovered healing medicine, and sometimes lethal mixtures. This DVD treats the history and origin of poisons and their use by man. The most common and most dangerous known poisons are introduced. A journey into the body unveils the secrets of the deadly substances and shows how poisons work and why some kill slowly and painfully while others take effect suddenly and unexpectedly. Many plants and fungi produce life-threatening substances. But animal poisons are unparalleled in their effects. These ex- periments of nature also inspired human preparers of poison as well as healers. The most mysterious cases from history and nature could be re-opened. With the help of the new findings, new cures might be developed.

Wenn Vogelarten die Jahreszeiten an unterschiedlichen Orten verbringen, werden sie als Zugvögel bezeichnet. Mehrere Milliarden von ihnen sind jährlich unterwegs. Alljährlich machen sie sich von ihren Brutplätzen auf den Weg in ihr Winterquartier und zurück. Dabei fliegen manche Arten Tausende Kilometer. Sie überqueren Gebirge, Ozeane und Kontinente. Es ist eine Reise voller Hindernisse und Gefahren. Wie finden Zugvögel punktgenau ihr Ziel? Sie haben mehrere Möglichkeiten: Mit ihrem inneren Kompass können sie das Erdmagnetfeld wahrnehmen. Wie sie das genau machen, weiß man noch nicht. Sie können sich aber auch am Stand der Sonne, der Sterne und anhand der Landschaften orientieren. Den Sonnenstand erkennen sie selbst bei bedecktem Himmel, da sie UV-Licht wahrnehmen. Durch Meeresbrandung entstehen tiefe, für uns unhörbare sogenannte Infraschalltöne. Auch danach können sich einige Vogelarten orientieren. Gemeinsam mit dem umfangreichen Unterrichts- und Begleitmaterial auf dem Datenteil der DVD ist der mehrsprachige Unterrichtsfilm bestens für den Einsatz im Unterricht geeignet.

Most of our earth is covered in water. Without water, no life. The water on our earth is in a constantly renewed global cycle. By evaporation the water gets into the atmosphere, by atmospheric circulation the evaporated water is further transported across long distances and returns to the earth as precipitation. Climate change, however, alters this hydrological cycle. Climate change intensifies the disparities in the global water supply and increasingly causes droughts and floods, respectively.

Die Gründe, warum Menschen aus ihrer Heimat fliehen, sind vielfältig. Ob Krieg, politische oder religiöse Verfolgung, Hunger oder Armut – letztlich ist die Situation für alle Menschen, die sich auf die Flucht begeben, in ihrer Heimat derart hoffnungslos und verzweifelt, dass sie sich ein würdiges Leben nur noch in der Fremde vorstellen können.
