Basics of Biology III
What is the importance and function of enzymes? The lock-and-key principle is explained and, based on amylase and katalase, the dependence of reaction speed and intensity of effect on temperature and pH-value can be seen. With microscopic pictures and graphs the structure of animal cells is explained. But their appearance is very different depending on their functions. Nerve cells differ from blood cells just like the latter from sperm cells. A tissue is a combination of many cells that perform specific functions in the body. Any kind of growth of an organism is only possible when new cells are created. The process of cell division is called mitosis. This is then differentiated from the multiplication of reproductive cells, as in them the number of chromosomes must be reduced to half. Impressive shots and graphs illustrate these processes. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.

New York City
A global metropolis of superlatives: the world capital of trade and culture is bustling with 8.1 million people from all nations. Due to its sea port, New York City became increasingly significant in the 19th century, before proceeding to transform into a unique megacity. Formed by immigration and commodity trade, the city today is above all known for its stock exchange, culture, the UN headquarters and its tourist attractions. This didactic DVD offers a clearly structured overview of the city on the east coast of the United States. In the first four chapters, maps and impressive pictures give an overview of the geographical situation of the city, its history and politics as well as education, language and traffic in the metropolis. Important sights and an insight into the lives of its inhabitants can be found in the last chapter. As a special feature, we offer a film from 1967 on New York City. Both films are excellently suited for comparison, on the one hand with respect to the city’s historical development and on the other hand with respect to the presentation on film.

School Caching
A treasure hunt in nature… and with GPS devices! Geocaching has been a real trend with lovers of nature for long and now more and more schools discover that pupils can be encouraged to head out into nature and, moreover, that learning content can be communicated creatively in this way. The pupils get the coordinates for the next station only by solving a maths problem, for example, or the various answer options are linked to coordinates. In addition, geocaching promotes thinking and working in groups and can be used to improve classroom community. In this DVD, a school class demonstrates us a school caching organised by their teachers in the Swabian Alps, the development of an educational cache and how GPS works. With the extensive accompanying material the didactic DVD is ideally suited for use in the classroom.

Europe
According to many scientists, the beginnings of Europe go back to antiquity, and there specifically to the freedom and democracy of the Greeks. Others consider the foundations laid as late as in the Middle Ages. But the settlement of the area we call Europe today began far earlier. The key periods of our European history are to explain how Europe became what it is today.

All Is Number
“All is number“, this saying already applied in the 5th century B.C. when the brotherhood of the “Pythagoreans“ was founded. Natural, rational and irrational numbers have been an important concept since the creation of the Bible, throughout antiquity up to our modern times. The Fibonacci Numbers, for example, have not only found their use as a numerical pattern in mathematics, they have also been immortalised in art and painting. In this film different and amusing approaches to mathematical methods and processes are illustrated with vivid images, which facilitate pupils’ understanding. In many things that we handle every day fascinating numerical proportions are hidden. Squaring the rectangle and the circle play an important role thereby. Since Greek antiquity the Golden Ratio has been considered to be the epitome of aesthetics and harmony. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.

Energy-saving Lamps
Energy-saving lamps are energy-efficient illuminants which will step by step replace energy-intensive illuminants. This replacement has been laid down in an EU framework directive. This directive has resulted in two laws, according to which, for example, conventional light bulbs are to be replaced by energy-efficient lamps such as compact fluorescent or halogen lamps.

Sigmund Freud II
At the beginning of the year 1900, Freud lived in a scientific isolation that he himself referred to as a kind of “splendid isolation” that allowed his ideas to develop without interference. It was the time when the results of the research on psychoanalysis began to show consistency. In his private life, Freud took care of his family and friends. Finally, on 1st April 1902, he was appointed honorary professor after his application with the university had been rejected several times due to his Jewish origins. In 1905 Freud published “Three Essays on the Theory of Sexuality”. The book caused a scandal. Psychoanalysis still met with objections, criticism and indifference. QUOTE FROM SIGMUND FREUD “Psychoanalysis as a science is not characterised by the matter it treats but by the technique it employs. It intends and does nothing but the disclosure of the unconscious of the psyche.”

Dictatorships in the 20th Century III
Today, the Caribbean island state of Cuba is an independent republic. Cuba was first ruled by the Spanish and later by the USA before the island gained its independence under Fidel Castro in the 20th century. He grew up in privileged conditions but already while studying law he engaged in political activity. He fought against the corrupt dictator Batista, who was supported by the USA, and later against the USA itself, and during the “Cold War he is a loyal but dependent ally of the Soviet Union. In 1962, the world is on the brink of an atomic war. As a consequence of the break up of the USSR and the continued embargo by the USA, the island sinks into poverty. Castro remains in power although he encounters more and more resistance in his own country. In 2008, he abdicates due to illness. The didactic DVD “Dictatorships in the 20th Century III – Fidel Castro“ tells the story of the man whose life is inseparably linked to the history of the island of Cuba in the 20th century. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.
