Tornadoes come from cumulous nimbus clouds. These clouds are made up of warm air that rises and falls. This constant up draft and down draft comes together and starts to spin. The more it spins, the faster it moves sucking up more and more air. If this touches the ground, a tornado is born. Tornado strength is calculated on the Fujita Tornado Scale ranging from F0- F5 depending on wind speed. A tornado moving 65 miles per hour is considered an F0, which has little damage. A tornado can move over 200 miles per hour, classified as a F5, and can destroy everything in its path.
This book would be great to use during a science lesson on weather. After reading this book with the class, I would have the students make a brochure about tornado safety. Some safety tips are listed in the back of this book and more could be found through research. This brochure should instruct someone on exactly what to do if a tornado was coming their way. It will also inform them on the Fujita Tornado Scale and the national weather service.
