Question #1 sample answer:

  The four major changes in society as man left the Neolithic age were settlement in communities, domestication of animals, development of agriculture, and craftwork.

 

1. What four major changes occurred in society as Neolithic man left the Stone Age?

 

Z. What steps must be taken to make a cast metallic object useful (i.e., what must be done immediately after removing the object from the mold?)

 

3. List in step-wise fashion how man progressed from craftwork to smelting of metals.

 

4. What modifications did the Chinese make in metal working to allow them to cast metals?

 

S. Discuss how early man would have used native metals (including meteoric iron).

 

6. Before any metal can be smelted from its ore two conditions must be established. Discuss the equipment and conditions necessary for smelting to occur.

 

7. Discuss pottery making and how metal samples were first isolated during this process.

 

8. To improve the process of copper smelting 4 ideas were presented. List several of those.

 

9. Why was copper not useful in early metal working?

 

10. The wrought iron process of metal working involved both steeling and tempering. Discuss the steeling process in terms of how iron becomes a more useful product.

 

11. Alloys are mixtures of metals melted together. Describe why the addition of tin to copper is so beneficial.

 

12. Describe why the Bronze Age came to such an early end.

 

13. Why was the process of casting superior to early wrought iron working.

 

14. Tell why the theory of camp fires first smelting copper is not valid?

 

15. Explain what our society might have been like had we not so fully developed the use metals or had our planet not been so rich in easily obtainable metals.

 

16. The growth of our civilization has coincided with our ability to create hotter and hotter fires. Explain how this is so.

 

17. The process of tempering wrought iron is often poorly presented in movies. Explain what is often left out of movies and why these extra steps must be done to make a good product.

 

18. Describe the existence of early Stone Age man.
