Ask AI: How to create the Zhang Heng Seismograph

1. Gather the materials needed for the seismograph including a pot, a length of rope, a weight, and a pendulum. 2. Using the rope and the weight, create a pendulum by tying the rope to a pot. 3. Hang the pendulum from a secure place with the pot below it. 4. Attach the pendulum to the ceiling or a wall using the rope and secure it in place. 5. Adjust the weight of the pendulum so that it is able to swing freely without hitting the pot. 6. Create a track or groove in the ground to represent earthquakes by using a stick, stone, or other object. 7. Place the pendulum above the track and make sure that it is secure and able to swing freely. 8. When an earthquake occurs, the pendulum will swing and the pot will move along the track, indicating the presence of an earthquake.
