“Geocaching” is a proven way to bring fun into the Geosciences classroom. But in what way can geocaching improve spatial thinking and social skills alike? This contribution describes results from a project which is currently organized by two schools in the Greater Munich area. The scientific support comes from the University of Applied Sciences in Karlsruhe. Results from the ongoing project show significant improvement, not only in spatial, but also in social skills for the participating students. Especially weaker students gained self-assurance and respect among their peers, as well as learning to estimate distances and thus to be more punctual and self-confident, even in unknown environments.
