  1. The Earthquake Detector(based on Zhang Heng’s Earthquake detector) This device will predict when earthquakes happen.

  2. Gathering Evidence Zhang Heng was an ancient Chinese architect. One day, he built a very accurate Seismascope.

  3. Identifying Causes • Zhang Heng’s invention might have been able to save lives in past earthquakes, like the one in Japan.

  4. Evaluating a Policy • If Zhang Heng’s earthquake detector was still being used today, every country, depending on size, should have multiple earthquake detectors.

  5. Developing Solutions • This video explains Zhang Heng’s Earthquake detector. I recommend watching it. • http://www.youtube.com/watch?v=GcVFuIccf5c

  6. Selecting best solution • Zhang Heng’s earthquake detector could still be used around the world today. • The earthquake detector will be able to save lives • According to Chinese history, Zhang Heng’s earthquake detector detected an earthquake.

  7. Benefits and Costs • The earthquake detector will be able to save lives and save money that would be spent on medical treatments and repair jobs. Since this invention does not use electricity, the only money spent will be the supplies.

  8. Political Strategies • At a UN meeting, we could vote on using Zheng Heng’s earthquake detector. It could be very useful.
