The first part of this book describes the different kinds of rocks, soil and mountains found on our planet, and explores how they came into being. This section deals with the depths of the earth, and the long ages of time. In contrast, the second part examines the heights of our universe, in the movement of the sun, moon and stars. These bodies give us our sense of day, month and year. Throughout, Kovacs links the phenomena he's describing with human experience, how they affect people in different parts of the world. This is a resource for Steiner-Waldorf teachers for Classes 6 and 7 (age 11-13).
