Hands-on Biology
To perform the experiment with beans you need first of all the seeds, of course. Runner beans are well suited for it. Watch out! Eaten raw, bean seeds are poisonous! For the germination experiments you need one plant pot per experiment. You need a waterproof pen for labelling the pots. Moreover, a watering can and water are required to keep the plant soil moist which is also needed. Some of the plant soil should be dried beforehand. To exclude the light you need a carton, to exclude the air a solid, transparent plastic bag and to exclude the soil cotton wool. In addition, scales, a glass and a protractor are required.

On Fire!
This DVD provides information on the history of fires and the fire brigade. The firefighters’ job is vividly illustrated, including their tasks and equipment. The topic of placing emergency calls plays a major part on this DVD. For safety training pur- poses, fire brigade operations are shown, causes of fires dis- cussed and extinguishing fires is practiced. In particular, the appropriate conduct in the event of a fire (alarm, test alarm, escape route, emergency call, fire detector, fire extinguisher, etc.) and first-aid measures for burns are demonstrated. The fact that besides the familiar fire engine, there are also fire brigades on water, on land and in the air shows how diverse this job is. A visit to the youth fire brigade makes this DVD especially suited for primary school pupils.

Our Weather
In everyday life we are confronted with this topic on a daily basis. It is part of our lives. The weather determines our daily routine more than we tend to think. Children, in particular, have a lot of questions on the subject. How does the weather form? What different forms of clouds are there? How is a weather forecast made? Why does it rain? These are only a few of them. The film looks into these questions and answers them in terms and pictures suitable for young pupils. Looking to the future, the problems of climate change and greenhouse effect are also dealt with. In addition, the film conveys to the children how important it is to treat our earth with sensitivity. As a special bonus, this DVD offers fast-motion picture material from weather stations as well as satellite pictures made available by the German meteorological service, which can be accessed via the DVD menu. Together with the didactically arranged accompanying material, this DVD is perfectly suited for the classroom both as an introduction to the complex topic of the weather and as a tool in the hands of the pupils when working individually or preparing projects.

Die innere Uhr
Der Faktor Zeit bestimmt unser gesamtes Leben. Manchmal scheint sie dabei still zu stehen und manchmal scheint sie nur so zu rennen. Zeit ist zwar eine physikalische Größe, die sich durch Uhren bis auf Millisekunden messen lässt. Das tatsächliche Zeitempfinden ist aber bei jedem Menschen individuell unterschiedlich. Woran liegt es, dass dem Einen eine Stunde ewig lang vorkommt, der Andere aber das Gefühl hat, es sei nur ein Augenblick vergangen? „Schau dich schlau!“ will wissen: Was ist mir unserem Zeitgefühl los? Was bedeutet Zeit überhaupt?

From Hatchling to Swan
This native water bird glides majestically across the water. It has a graceful curved neck. But how does a small “grey duckling“ change into an “elegant swan”? At the age of two to three years, Mute Swans can have swanlings and set out to find a mate. Already in autumn, the mating time for the Mute Swans begins, mating birds, however, can be seen until March. Here, Mute Swans show a behaviour quite unusual in Anatidae: males and females court each other.

Units of Length
The DVD starts with a look back into the past. How did peop- le measure in former times? What historical units of measure- ment were there? What is the standard metre? Since when has there been a system of units? Subsequently, the units of measurement – metre (m), centimetre (cm), milllimetre (mm), decimetre (dm) and kilo- metre (km) – are examined more closely. In a third chapter, an overview of the conversions is presented and their systematics explained. Decimal points and the prefixes are clearly illustrated. Then the DVD offers a digression visiting other countries and their length units. America and Great Britain, with inches, feet, yards and miles, play a central role. In the fifth chapter, calculations using scales are presented. Here the focus is laid on scales in maps, but also scaling down and up are dealt with. In the last chapter, circumferences of rectangles and squares are measured and calculated with various examples.

Licht und Farbe
Ohne Licht würde auf unserer Erde kaum Leben existieren. Pflanzen brauchen diese elektromagentischen Wellen, um zu wachsen und durch den Vorgang der Photosynthese unter anderem Sauerstoff zu produzieren. Genauso sind Farben wesentlicher Bestandteil in der Natur und haben ihre eigene Bedeutung. Auffällige Färbungen bei Reptilien sollen Gefahr signalisieren, während ein möglichst prächtiges Federkleid bei Vögeln ihre Attraktivität steigern soll. Genau wie andere Arten reagieren auch Menschen auf Licht und Farben. „Schau dich schlau!“ zeigt, wie die beiden Komponenten eingesetzt werden, um uns Wohlbehagen zu bescheren oder uns zum Beispiel zum Kaufen zu animieren.

Solar Energy
80 % of our current energy needs are covered by fossil fuels (coal, oil, gas). Their supply may soon lead to severe problems as worldwide stocks will be exhausted one day. That is why the future belongs to renewable energy from sun, wind, water, and biomass. The Sun as an inexhaustible energy source is estimated to be available to us for another 4.5 billion years to come. It supplies us with “clean energy“ that is available everywhere on earth and that exceeds worldwide energy needs many times over. The film presents the pupils with the long history of solar energy use. The functioning of solar collectors, solar cells and solar power plants is explained, the current operating ranges of solar technology are dealt with and an outlook for the future is provided. With the act on the phasing-out of nuclear energy Germany has taken over a pioneering role worldwide in the field of renewable energies. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.

Greek Mythology
The search for the origin and meaning of our existence has always been an integral part of the history of mankind. The religion and myths of the ancient Greeks with their impressive realm of gods were influenced by the oldest advanced civilisations of Mesopotamia and Egypt, spread their impact in Hellenistic and Roman times and have retained their influence on the culture of the Western world until today.

Ways to Democracy
This film shows the most important stages on the way to the development of democracy in Germany. It begins with the foundation (1792) and quick end (1793) of the Republic of Mainz in the course of the French Revolution, gives an account of the Hambacher Fest in the pre-March era and the failed revolution of 1848/49, contemplates the democratic development in the German empire and the late realisation of the first German democratic national state in the Republic of Weimar. Other important steps are the erosion of the Weimar constitution after 1933, Germany’s transformation into the national socialist dictatorship and World War II as well as the formation of different democratic models in West Germany and East Germany after 1945. Finally, it is described where the rules of democracy can be explained and practiced today and what current dangers there are to the democratic system of government. The aim is to make pupils aware of the fact that democracy must not be taken for granted – it is a historical legacy that we always have to safeguard.
