CHINESE INVENTIONS
2
Gunpowder
  • Gunpowder is also known as black powder.
  • It was invented around 1040.
  • The Chinese put gunpowder into bamboo sticks and
    they used them as firecrackers.
  • Today they use gunpowder to make fireworks.

3
The Compass
  • The compass was made around 200B.C to 200A.D.
  • The earliest record of the compass was made by a
    spoon shaped compass made of loadstone or
    magnetite ore.
  • The compass at that time could only point south
    but the ancient Chinese realized that the
    magnetite ore would point towards a magnetic
    north.

4
Silk
  • The Chinese were the only ones who knew the
    secret of silk until other people found out.
  • Silk is made from silk worms.
  • Silk is very expensive and very strong.

5
Paper
  • Paper was made by the Chinese 1,800 years ago.
  • It was made out of bark and hemp.
  • In the southern part of China like in the
    Guizhou province they might still use the old way
    of making paper.
