Neuronen
Was wir fühlen, wie wir reagieren, das wird gesteuert durch die Nervenbahnen unseres Gehirns. In dem Film wird das Nervensystem dargestellt und der Aufbau der einzelnen Nervenzellen erläutert. Welche Übertragungswege ein Reiz nimmt und auf welchen Wegen eine Reaktion ausgelöst wird, wird in anschaulichen Grafiken gezeigt.

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.

Basics of BIOLOGY I
Basics of Biology examines general biological issues that help to expand and consolidate basic biological knowledge. The first film of this series deals with the structure of the plant cell. It centres around the structure and function of plant tissue such as the xylem, root cells and stomata as well as the functions of the chloroplasts. In the second chapter the issue of photosynthesis and the elements involved in it are dealt with. With tests and experiments impacts of light and CO2 on photosynthesis are demonstrated and explained. The third part explains human respiration. The rising oxygen consumption of a woman athlete brought on by physical effort on the moving walkway is shown. What happens when the physical stress becomes too strong and the amount of oxygen inhaled is no longer sufficient? The transition from aerobic respiration to anaerobic respiration is vividly illustrated. Together with the extensive accompanying material the didactic DVD is ideally suited for use in the classroom.

Infections
’Health isn’t everything but everything is nothing without health.‘ – This clever sentence comes from the German philosopher Arthur Schopenhauer. Since the introduction of antibiotics we are hardly aware of infectious diseases as a threat to our health anymore. However, how important successful prevention and therapy are is shown in the fact that in Germany alone about 50,000 deaths are caused by infectious diseases every year. Infections are the second most common cause of death worldwide. According to an estimate of the World Health Organisation more than 30% of deaths worldwide are related to infectious diseases. Most of them affect people in poorer countries and over 15 million people die of infections worldwide.
