  2. History Paper is writing material made from wood pulp or other fibrous material. Almost 5,000 years ago, in ancient Egypt, the papyrus plant was processed and used as paper. Papyrus paper was made from thin sheets of papyrus pith that were soaked in water, pressed together with the grains at right angles, and then dried - the sticky sap of the plant made the thin sheets stick together, forming a sturdy writing surface. Papyrus (Cyperus papyrus is its genus and species) is a grass-like aquatic plant native to the Nile valley of Egypt. Our word paper comes from "papyrus." Paper is made by grinding plant material into a pulp, forming it into thin sheets, and drying it in a form. This process was invented in AD 105 by Ts'ai Lun, a Chinese official and member of the Chinese Imperial Court, about 2000 years ago; he originally used the waste from silk production. Early Chinese paper was made from the bark of the mulberry tree and other plant fibers.

  3. economy Silk: The silk from the silkworm's cocoon is a single, continuous thread. It is made of a protein that head. The Chinese have harvested silk from silkworm cocoons for thousands of years. To harvest silk, the silkworm is allowed to spin its cocoon and it is then put in boiling water to kill the pupa and help unravel the thread. Each cocoon contains a single silk thread that is about 300 to 900 meters long. The silkworm has been domesticated to the point where it could no longer survive in the wild. The adult moth cannot eat or fly; it has a fat body and small wings.

  4. culture China's national flag was adopted in September, 1949. This flag was first flown in Tiananmen Square on October 1, 1949 - the day of the founding of the People's Republic of China. The rectangular flag has a red field with five golden-yellow stars (each with five points) in the upper left corner. The star on the left is larger than the other four. The red color of the flag symbolizes revolution. The large star symbolizes the Communist Party (which rules China) and the smaller stars represent the people of China.

  5. fun facts Gunpowder was invented in China, probably during the 1000's. Gunpowder is composed of about 75 percent saltpeter (potassium nitrate), 15 percent powdered charcoal, and 10 percent sulphur. The Chinese used gunpowder to make fireworks and for signal flares. Gunpowder was also thought to have uses in medicine and in alchemy (the "science" of trying to change non-precious elements into gold). Soon after its invention, the Chinese used gunpowder for weapons (which they called fire arrows). Fire rockets were made by filling capped bamboo tubes with gunpowder and iron bits (shrapnel). These lethal weapons were attached to an arrow, lit, and shot from a bow. These were the first solid-fuel rockets. The Chinese used them to fight the invading Mongol hordes.

  7. Geography The Great Wall of China was built over 2,000 years ago, by Qin Shi Huangdi, the first emperor of China during the Qin (Ch'in) Dynasty (221 B.C - 206 B.C.). In Chinese the wall is called "Wan-Li Qang-Qeng" which means 10,000-Li Long Wall (10,000 Li = about 5,000 km).
