Learn moreAltersarmut
Innerhalb von 52 Jahren hat sich in der Bundesrepublik das Verhältnis von Beitragszahlern für die Rente zu den bestehenden Rentnern um den Faktor 3 verschlechtert. Sind 1962 noch 6 Erwerbstätige für die Rentenzahlung eines Rentners aufkommen, so mussten 2014 zwei Erwerbstätige für die Rentenzahlung von einem Rentner aufkommen. Die Altersarmut in Deutschland steigt. Denn nur wer 40 Jahre ohne Unterbrechung mindestens 2.100 € verdient hat, bekommt als Rente mehr als den Hartz-IV-Satz ausgezahlt. Beschäftige im Niedriglohnsektor oder in Teilzeit können selbst nach 45 Jahren Arbeit nicht von ihrer Rente leben. Vielen Rentnern bleibt nur der entwürdigende Weg zum Arbeitsamt.

Oh, what’s that? Original soundtrack Thissen: “As our children grow up in a media world and naturally handle the media, they should also be a topic in school.“ An older child says the point is that they don’t just load down apps but create things themselves that haven’t existed so far. Hi, I’m Jana. A propeller hat. I’ll put it on. Now I’m no longer a simple rhino, but a flying rhino. Original soundtrack Thissen: “It’s exactly the great flexibility of tablets that promotes very personalised and adapted learning.” Original soundtrack Welzel: “It’s fascinating to see how the children grow with their products and how they always want to improve them.” The Westminster Abbey is a church in London for the royal family. Original soundtrack Welzel: “And?“ They think it is ok.
Learn moreInteractive Whiteboards
Although the computer found its way into school some time ago already, it has mostly led a marginal existence so far, banished to extra practice rooms or to the side of the classroom. With the new medium of the interactive whiteboard the computer promptly becomes the focus of the lessons as the central hub. On the digital board that projects contents via a beamer like on an oversized computer monitor, pictures and texts as well as audio and video files can be displayed. The possibilities of representation on this new white board, the whiteboard, seem to be almost unlimited compared to the traditional blackboard. But with the help of the board things cannot just be better represented, the computer-connected board can, in addition, be used by teachers and pupils as a universal tool. On it, content in a new - that is interactive - form can be searched online, organised and presented in the classroom.

While large parts of Europe still lived in the Dark Middle Ages and huge cathedrals dominated the cities, a new consciousness blossomed in Florence, Italy at the beginning of the 15th century:

Learn moreThe 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.
Learn morePenguins
Most people know penguins only from the zoological garden. There they arouse many visitors’ interest. This is, on the one hand, because of their peculiar black-and-white colouring, which reminds you of a tail coat, on the other hand, because of their upright walk. We find penguins amusing or funny; but if we knew more about their extraordinary skills, we would not laugh about them but gaze at them in wonder and reverence.
