Introduction

5 min

Read aloud

In AD 105 a court official named Cai Lun presented a cheaper way to make paper. In 132 Zhang Heng built a device that detected distant earthquakes. Students explore how Han inventions spread along the Silk Road and changed the world.

Class discussion

14 min

Pick two or three. They run from what happened to why it mattered.

  1. Before paper, Chinese writers used strips of bamboo and pieces of silk. Why was paper such an improvement?
  2. Paper existed before Cai Lun, yet he got the credit. Why do inventions often get linked to one famous name?
  3. Zhang Heng's device could report an earthquake hundreds of kilometers away. Why would an emperor want to know quickly?
  4. Paper reached the Islamic world in the 700s and Europe even later. How might history have changed if it had traveled faster?
  5. Which Han invention do you think changed daily life the most, and why?
