ABSTRACT
The Group IV was divided for its activities, which centered around the historical development of the fundamental occupations with special emphasis upon the progress made in methods due to invention and discovery. The spirit of inquiry is opening the door to investigation, to discovery and invention. The child is led to consider imaginatively the needs of other times and places which call forth certain kinds of occupations and the devices and inventions that gradually take place in them. The natural setting of man and his occupations, the basis of their future, was clothed with human significance to these little actors of primitive life as they imaginatively wandered in the sand-box hills and valleys of their tribal habitation. In the process, many scientific facts of geology, of chemistry, of physics, or of biology, found their way into the sinews of their intellectual wings.
