A treasure hunt in nature… and with GPS devices! Geocaching has been a real trend with lovers of nature for long and now more and more schools discover that pupils can be encouraged to head out into nature and, moreover, that learning content can be communicated creatively in this way. The pupils get the coordinates for the next station only by solving a maths problem, for example, or the various answer options are linked to coordinates. In addition, geocaching promotes thinking and working in groups and can be used to improve classroom community. In this DVD, a school class demonstrates us a school caching organised by their teachers in the Swabian Alps, the development of an educational cache and how GPS works. With the extensive accompanying material the didactic DVD is ideally suited for use in the classroom.
