The search for the secret mineral code

From 8 to 16 June 2019, the terra mineralia will be a mysterious place, because visitors of all ages will be taking part in a scavenger hunt through the mineral exhibition of the TU Bergakademie Freiberg.

Discovery boxes are hidden in the entire exhibition. They contain hints and questions about various minerals. At the end, the answers result in a mysterious mineral code, which is decoded in the hands-on laboratory "Forschungsreise". There the girls and boys enter their code into a mineral generator. If it is correct, the machine "spits out" a real mineral.

These minerals can then be determined by the children themselves. Like a real mineralogist, they examine the various properties such as color, line color, breakage, gloss and much more. The students of the TU Bergakademie Freiberg are there to help until the solution to the mystery is found. Of course, the self-determined mineral can be taken home at the end.
