Experimenting at the Rhätischen Bahn AG
Experience science up close: On May 27, 20 high school teachers from various schools in Graubünden were given exciting insights into the world of nanotechnology at Rhaetian Railway Ltd. in Landquart. The event for the STEM promotion project “SimplyNano 2” offered practical experiments, exchange and inspiration for the classroom.
All participating schools were then able to take away free class sets of the “SimplyNano 2” experiment kits. These contain 41 illustrative experiments and make it possible to experience the fascinating nano world directly in the classroom.
The core of the training was independent experimentation. The teachers tested various experiments from the “SimplyNano 2” experiment kits, which were specially developed for use in schools. Among other things, two special materials caused great amazement:
- Aerogel: This extremely light material has a nanostructure that repels liquids particularly effectively. In the experiment, it was demonstrated that even sticky honey simply rolls off the surface.
- Lotus effect: The participants observed how water rolls off plant surfaces, taking dirt particles with it. This principle of the lotus flower is used in self-cleaning facade paints, glass coatings and textiles.
Visiting the Rhaetian Railway AG in Landquart
The training course was hosted by Rhätische Bahn AG in Landquart. RhB has been connecting people, places and cultures in Graubünden for over a century and, with over 1,800 employees, is one of the canton’s most important employers. At the Landquart site, the participants were given a practical insight into the world of public transport, railroad technology and the diverse professional fields that enable the safe and reliable operation of the Rhaetian Railway.
At the same time, the teachers were given an insight into the training opportunities at RhB. The company trains over 100 apprentices in various professions, making it one of the leading training companies in the region.
Support from the region
The experiment kits and all associated teaching materials are available to schools free of charge. The project is made possible by the support of various foundations, companies and associations. The SimplyScience Foundation is the publisher of the offer. The teaching materials were developed by Innovationsgesellschaft St. Gallen, which places particular emphasis on practical, understandable and easy-to-implement lessons.
