This is an awesome and informative nonfiction book that teaches the reader about the science of tornadoes. This book also provides information on the different rankings of tornadoes, what to do during and after a tornado, and several facts about tornadoes. The author, Gail Gibbons has written over 50 informational children’s books on different subjects. The amount of books she has written and had published leads me to believe that she is a very qualified author. The illustrations in this book are great, and depict what kind of damage tornadoes of different sizes can cause. The author provides a couple of websites and suggested search words for readers to explore the subject further. This would be an excellent book for a science teacher to use when teaching students about weather.
