Wetter
„Nach Regen kommt oft Sonnenschein - Das Wetter“ „Schau dich schlau!“ nimmt heute die verschiedenen Wetterbedingungen unter die Lupe. Wie entstehen Wind, Gewitter, Regen und Hagel? Außerdem zeigen unsere Moderatoren Joey Grit Winkler und Fero Andersen, wann die verschiedenen Wetterlagen für den Menschen gefährlich werden können. Im Selbstversuch testet Fero Andersen, bei welchen Windstärken ganz normale, alltägliche Tätigkeiten wie Frühstücken, Zeitung lesen oder Rasieren überhaupt noch möglich sind. Außerdem beweist er, dass ein teurer Regenschirm nicht unbedingt der Beste sein muss.

Breakfasting – this morning ritual exists in almost every country, every culture and every century. However, food, time, process and duration vary from country to country, family to family, person to person. The first meal of the day is of particular importance. It allows us to fully wake up. Around the table, the day's schedule is planned. Here is where the family meet. Above all, breakfasting is important for children. When they get up, the energy storage from the previous day is empty because the body consumes energy also during rest and sleep. A healthy, substantial breakfast helps us to gather new strength.
Learn moreAll 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.

The turnaround in energy policy is meant to lead away from the old system of centralised power stations, from the conventional energy sources such as coal, oil or nuclear power. Instead, energy is to be generated in a lot of smaller installations from renewable sources such as sun or wind. That leads to a new structure of energy supply. The turnaround requires a new, intelligent system with which the energy exchange between generator and consumer will be controlled in the future. The English term “smart grid“, which translated means nothing other than ’intelligent electricity network’, represents this system of the future.

This DVD treats the different working and living conditions of people in the Ruhr valley around the year 1900 and refers to the thesis of the sociologist Li Fischer-Eckert. She conducted interviews with working class women on their living conditions in the workers’ housing estates in 1911 and 1912. Based on her findings, she divided the workers in four classes: The first one has a “cosy home without luxury or deprivations”, those in the second class live “on the verge of deprivation”, the poorer workers “are defeated by unfavourable conditions” and those in the fourth class live in “complete neglect”. With the kitchen-cum-living-rooms set up in the Ruhrland Museum, which are shown and described in the film in an impressive way, a direct insight is offered into the workers’ lives. Furthermore, work in heavy industry and mining, the strict reign of the employers as well as the changes in social policy and the workers’ fight for their rights are discussed.

A new era began for South Africa when, in 1886, an out-of-work miner struck gold at the Witwatersrand in South Africa. The consequences of the discovery of the world’s largest natural treasure were dramatic. From all over the world speculators and adventurers flocked to the area. Scattered »gold fever« shanty towns mushroomed, which soon developed into modern concrete cities, though. The wealth created by the gold made South Africa grow into an industrial and financial power. Today, the economy of the country is the most important of the entire African continent. But there are many pitfalls. It is imperative to recognise them in order to confront the challenges of the future.
Learn morePeriodic Table
With the help of the periodic system chemists can predict properties of chemical elements and derive chemical reactions. But you need not be a chemist to understand the periodic system.
Learn moreNoble Gases
Xenon, Helium, Neon, Argon, Krypton and the radioactive Radon belong to the noble gases. These form the family of noble gases as the elements of the eighth group of the periodic table. All of them are colourless and odourless, non-inflammable and non-toxic. Their most striking chemical property is their inertness. This can be explained by their electron arrangement, termed noble gas configuration and represents a particularly stable and therefore low-energy state. The noble gases are to be found in scant amounts in our air from which they are also distilled. Helium is mainly extracted from natural gas. In everyday life, we encounter noble gases for example as shielding, filling or buoyant gases and in fluorescent tubes. The shell model describes the structure of the atoms. It is based on the distribution of electrons in restricted areas at a fixed distance around the core of the atom.
