ENERGIE-ALLEE The magazine of the juwi group JUNE 2015 SOLAR FUTURE Solar energy has great prospects worldwide. It also no longer has to shy away from profitability comparisons. WALKING THE TALK THE HOME FOR LITTLE RESEARCHERS While the employees at juwi are planning wind parks and solar plants, their children are experimenting with the elements of nature next door in the company day care center “juwelchen”. 2 ENERGIE-ALLEE | JUNE 2015 EVA SCHNEIDER has been working as educator in the “juwelchen” since December 2011. Here she mainly works with the children in the pixy group (“Wichtelgruppe”) and the research lab. She also guides visitors who want to study the pedagogical concept of the kindergarten. In 2014, she welcomed 120 guests from 22 institutions. he salt trickles slowly into the water glass. Raja and Rio take another pinch. And then another. The two look closely at Twhat happens with the sun flower oil which floats in a finger-thick golden-yellow layer on top of the water. “It’s making little bubbles,” Raja notes. And indeed: the oil which bonds to the salt sinks in small droplets to the bottom of the glass. It looks like magic, but it’s a result of physics: oil is lighter than water, but when it is combined with salt it becomes heavier. In order to make the experiment more vivid, the day care teacher Eva Schneider handed out food coloring beforehand. Red, green, yellow. This makes the bub- bles which Raja and Rio are creating in their glasses along with Moritz, Nola, Jonas, and Elena, look a lot like the up and down of the colorful fluids in a lava lamp.
