News Maustag 2026: Geosciences with die Maus! On 3 the 3rd of October 2026, the Institute of Geosciences again opened its doors to young explorers as part of the nationwide event ‘Türen auf mit der Maus’ (Open Doors with the Mouse). The children were invited to take part in a varied hands-on workshop: at different stations, they could grow crystals, examine rocks under a magnifying glass, recreate layers of the Earth in cups and sift small minerals from sand. Guided by enthusiastic helpers, the children playfully discovered the world beneath our feet and were rewarded with a real geologist's certificate at the end. A big thank you goes to all visitors, volunteers and the student council, who ensured a great atmosphere with fresh waffles. We are already looking forward to the next edition next year! 📷 A short video with impressions can be found on our social media channels. Previous Next
