Zhang Heng and the Incredible Earthquake Detector

One of the most helpful inventions in meteorology was created in China. Zhang Heng and the Incredible Earthquake Detector is about the scientist, Zhang Heng behind the first seismoscope or earthquake detector. Even though these devices have changed over time as technology has changed, they can still predict where and when an earthquake may hit. Zhang Heng was well known for his work in astronomy and math. I especially liked the use of dragons and toads around the machine.

The illustrations in this book are absolutely incredible. The vivid colors in the illustrations help to tell the story and demonstrate the dragons. The glossary in the back of the book is great for words I didn’t know. This is a great book and I recommend it.
