Enzymes

Almost every biochemical reaction in living organisms is regulated and controlled by enzymes. Without enzymes we could not breathe, digest food and the hereditary information in our cells could not be repaired and copied.

Slow Worm

The slow worm is a small, completely harmless lizard, which – contrary to its German name “Blindschleiche”– is perfectly able to see and is often mistaken for a snake because it has no legs and an elongated body. The German name is presumably derived from the Old High German word “Plintslicho”, which means “blinding sneaker”. This probably refers to the pretty, shining skin surface of the slow worm.

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.

Lichtverschmutzung

Die Elektrifizierung bescherte der Menschheit einen technologischen Quantensprung. Insbesondere die Möglichkeit elektrischer Beleuchtung dehnte die Produktivitätszeiträume der Menschen aus. Dass künstliche Beleuchtung durchaus als „Lichtverschmutzung“ mit negativen Auswirkungen auf Menschen, Tiere und Pflanzen aufgefasst werden kann, ist eine vergleichsweise neue Erkenntnis.

Human Liver

Normally you do not feel it, it does not beat like the heart, neither can we feel it like the lungs when we breathe in and out – nevertheless, it is one of our most important organs: the liver.
