6. Let’s rate some tornado damage using the Fujita Scale!
Number your paper from 1-5.

7. The house on the left with its roof still largely intact would receive an F1 rating. The house on the right depicts a classic F2 level of damage: its roof is largely gone but its walls remain standing.
Corresponding tornado wind speed: mph  Arlington, Texas
March 29, 2000

8. This tornado left virtually nothing standing in any house on the block, though the debris is concentrated enough that an F5 rating would be too high. F4
Corresponding tornado wind speed: mph  Moore, Oklahoma
May 3, 1999

9. Winds dug up these shallow-rooted trees and scattered them like matchsticks.F1
Corresponding tornado wind speed: mph  Near Pierce City, Missouri
May 5, 2003

10. From lower right to upper right moving clockwise around the cul-de-sac, the damage to these houses would receive the following ratings: F0, F2, F3, F2, F1. The overall rating for this damage would thus be F3.
Corresponding tornado wind speed: mph  Oklahoma City, Oklahoma
May 8, 2003

11. An extremely intense tornado leveled these houses, leaving the foundation of the house in the middle background swept clean. F5
Corresponding tornado wind speed: mph  Bridge Creek, Oklahoma

12. How do we protect ourselves from tornadoes?
Meteorologists use doppler radar to track storms so they can alert the public. (tv/radio/phones/sirens)
We educate the public on how to prepare and shelter in the case of a tornado. (drills/teach it in schools)
Local and federal governments set up rescue, relief and recovery plans.

13. Rescue Relief Recovery
1Rescue: Fire & Police departments, gas & electric companies search buildings for survivors and dead, turn off gas and electric power.
3Recovery: Local governments
rebuild roads/schools/homes
2Relief: Army/DRAW/Salvation Army/Red Cross/Churches (Charities)provide basic needs like food/shelter, help people recover their valuables and clean up their property.
