Hans-Ulrich Schmutz develops a comprehensive concept for geography education at the upper secondary level in Waldorf schools, tailored to the developmental situation of the students. His consistent and carefully structured teaching approach covers topics from geology to fluid dynamics, crystallography, technology, economic geography, and extends to astronomy and paleontology. For all these subjects, the author provides interesting and new perspectives that can gradually lead to an understanding of the living world and the connection between Earth and humanity.
