astronomy observing, popularization, dendrochronology

The paper deals with the issue of astronomy observing involving applications in technological fields. This topic was chosen with respect to interdisciplinarity, potential to engage and develop the pupil's interest into deeper understanding of technological and physical principles. Pre-concepts of the pupils of the astronomy being isolated science is necessary to get over. Astronomical observing focused on popularization enables to describe the issue of dendrochronology, climate changing, knowledge of spherical astronomy, time measuring, body moving and the other fields. We describe own experience with a certification of this topic.
