3. Make a special study of the fears of very young children. How many

the fighting instinct be eliminated from the human race? Is it desirable
to eliminate it?

5. Make a study of children's collections. Take one of the grades and
find what collections the children have made. What different objects are

6. Outline a plan for using the collecting instinct in various school

8. Make a study of play by watching children of various ages play. Make

9. What are the two main functions of play in education? Why should we
