... and on solid ground
Before drilling cores and soil samples can be examined in the laboratories, they must be "pulled". For the young field researchers this means: It starts on the site of the emerging Campus day-care center with drilling poles, liners and a heavy drilling hammer. With a lot of effort soil samples are taken here - the ground is still slightly frozen. Thus the children don't only find out something about stratum, but also that the work of the geologists can be quite arduous.
