Wenn Frosche vom Himmel fallen

As incredible as it may sound, nature is still unbeatable and provides us with the most amazing inventions and phenomena, beyond human imagination. Bacteria that produce plastic or electricity, for example, or natural rocket propulsion or algae that may meet the energy needs of future generations with their supplies of hydrogen. How is it that frogs and fish fall from the sky, how does the dust from the Sahara reach the Caribbean and what lies behind the mysteries of the deep-sea methane oases? Yet nature has also invented modern technologies. A natural solar power plant, for example, provides an Antarctic lake with an agreeable water temperature, and the first functioning nuclear reactor existed in Africa two billion years ago. Nature even created the very first laser. Researchers around the globe are increasingly searching for ways of using nature's inventions for developing new products and concepts. One case in point are extremophile bacteria, which thrive at the baking temperature of 140 degrees Celsius. The resulting enzymes should prove fruitful in chemistry. But also chemosensors, which work like a dog's nose, and bulletproof jackets based on spiders' webs are visions that could profit from evolution's treasure trove.

30 kleine Abenteuergeschichten fur Kinder ab 3 Jahren. Toni, Basti, Merle und Marie sind die besten Freunde. Gemeinsam bestreiten sie Abenteuer des Alltags, die jedes Kindergartenkind kennt: Sie spielen Indianer, finden einen Frosch, backen Sand-Kuchen … Dabei begegnen sie immer wieder biblischen Aussagen und erleben eine Menge Uberraschungen. Geschickt zeigt die Autorin Irina Kostic («Sieben Jahre ohne Pommes»), wie schon die Kleinen biblische Werte im Alltag umsetzen konnen: z. B. sich versohnen, einander zuhoren und ehrlich sein.
