The trip to the coldest continent on Earth gave me not only data for scientific research, lifelong impressions, interesting acquaintances, but also the impulse to begin educational activities for schoolchildren. In the past, I often gave popular science talks to adult audiences, but never to children. But this year the situation has changed. I visited several schools in Petrozavodsk and Apatity and I want to share with readers my impressions and, to be modest, new experiences.
