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.

The Eurasian Eagle Owl
With a body length of 60 to 75 cm and a wingspan of up to 170 cm, the Eurasian eagle owl is the largest owl in the world. It is also referred to as “king of the night skies”. After being hunted and almost exterminated by humans, the population of the Eurasian eagle owl has started rising again since the middle of the 20th century. Nevertheless, according to experts, it is not secured yet. Destroyed habitats and disturbances at the breeding sites, for instance by climbers, as well as dangers from power poles still threaten the population of the Eurasian eagle owl today.

Blossoms
In impressive pictures several interesting biological topics are conveyed by this film: knowledge of the structure of blossoms, their variety of forms as well as significance and purpose of their colours and scents. Thus it becomes comprehensible why blossoms are so differently structured, how self pollination is avoided and which evolutionary achievement is behind the symbiotic interaction between blossoms and pollinators. Pollination is a “deal“: the plant offers the insects nectar in exchange for the transport of the pollen. Prerequisite for this is the mutual adaptation process of the blossom to the mouthparts of the insect and vice versa. That cheating goes on during this “business relationship” between plant and animal is illustrated with the example of flower mimesis. The perfect way in which blossoms succeed in attracting insects without offering them nectar in return is another highlight of this film. Together with the extensive accompanying material the DVD is perfectly suited for use in the classroom.

New Species in our Environment
More and more animal and plant species successfully spread far away from their original homes. They are organisms that with our assistance – or even alone – are disseminated further and further across the globe: they are called invasive species.

Fette und Öle
Das Verhältnis zu Fett ist zwiespältig. Die einen streichen es aus ihrer Ernährung, die anderen geben horrende Summen für kaltgepresstes Olivenöl und seltenes Arganöl aus, um gesunde Fette zu sich zu nehmen. Dabei braucht der menschliche Organismus Fett um richtig funktionieren zu können. "Schau dich schlau!" nimmt Öle und Fette wie Oliven- und Sonnenblumenöl, Butter und Margarine unter die Lupe und zeigt, warum unser Körper darauf angewiesen ist um seine volle Leistung bringen zu können. Joey Grit Winkler und Fero Andersen wühlen sich durch den Ernährungsdschungel und entlarven typische Fettfallen. Von welchen Produkten sollte man die Finger lassen, weil sie viel fetter sind als wir annehmen? Je besser ein Gericht schmeckt, desto mehr Fett beinhaltet es in der Regel. Denn Fett ist ein Geschmacksverstärker. So zum Beispiel in Käse und Wurstsorten, aber auch in Gerichten wie Pommes oder Fischstäbchen, die frittiert werden. Um nicht auf diese Leckereien verzichten zu müssen, zeigt Fero Andersen wie man richtig frittiert und dabei nicht mehr Öl als nötig verwendet. Wer mit Fett brät, läuft bei falschem Umgang schnell Gefahr, eine Explosion oder einen Brand zu entfachen. Deshalb zeigt "Schau dich schlau!", wie sich dieses unnötige Risiko vermeiden lässt und wie – sollte der Fall doch eintreten – ein Fettbrand gelöscht werden kann.

Amphibians
More than 350 million years ago, the evolution of amphibians set in. Amphibians developed from fish – a first step towards life on land. Diverse reproduction strategies, manifold forms of appearance and a broad spectrum of sizes, ranging from the tiny Brazil litter frog to the giant salamander, constitute the special characteristics of the class of amphibians. The pupils learn about the different respiration techniques and the particularities of the amphibians’ circulatory system as well as about their defining characteristics and their repro- duction strategies. Moreover, the threat to amphibian species posed by environ- mental poisons and the climate change is also discussed. This DVD leads the pupils into the fascinating, unknown world of amphibians, which still remains to be fully researched.
