The article contributes results of a pedagogical research on teaching geosciences at elementary schools. The purpose of the research was to evaluate the efficiency of using worksheets at geoscientific excursions and to determine the pupils’ and teachers’ attitudes against Natural History 8 classes. The work’s main purpose was to create such materials that could be useful for teachers by planning and undertaking fieldworks. As a result serves an electronic database of geoscientific POIs (points of interest) of Slovakia and its software interface, GeoGuide. Another outcome is a set of 15 universal worksheets designed to be usable on any field trip within whole Slovakia. Both of these aids have already performed well at preparing and undertaking excursions. And at the same time, a pedagogical experiment has shown that pupils equipped with worksheets at the fieldworks generally acquire more valuable knowledge than those without it. Using worksheets has always significantly improved pupils’ score at final testing.
