How can we transform tab water into snow? How does nature manage to clear our water? Children aged 3 to 12 will get answers to those questions at the Children's University of TU Bergakademie Freiberg which will be streamed on December 5 at tu-freiberg.de/junioruni.

Mascot TU-Lino will welcome boys and girls at 10 a.m. The Children's University kicks off with hydrogeologist Professor Traugott Scheytts experiments with water for kids aged 6 ot 12.

At 11 a.m. smaller kids aged 3 to 6 can experience a Science Show presented by reporter Joachim Hecker. With his radio broadcast «Heckers Hexenküche» at WDR he brings the fascination of science to families homes. On December 5 he presents "many questions and a show packed with answers" and explaines, why our voice sounds strange when it's recorded, how one can make a musical instrument from a shoe lace or whether tab water can be transformed into snow.

Participating children can paint a picture on the topics of the online children's lectures and win a voucher for the local book shop. To take part, please sent your drawing to junioruni@tu-freiberg.de or hand it in at Campus Cafe SIZ leaving your name, age and contacts. All participants will receive a scarf with mascot TULino.

The livestream will be available on December 5 at https://tu-freiberg.de/junioruni - no registration required.
