The tropical storm that became Katrina formed over the Bahamas in 2005.
Katrina was one of the costliest and most destructive hurricanes in U.S. history and was the third strongest hurricane to touch down on U.S. soil to date. Katrina devastated New Orleans and other Gulf Coast areas and is estimated to have killed over 1,800 people.
The anniversary of Katrina is a good time to plan for local weather emergencies, especially since it occurs at the beginning of the school year. Explore the weather-related and other natural disasters that your geographical area is prone to; then review your school's emergency procedures with students.
Extend the lesson to students' homes and other places they may visit (religious buildings, for instance), asking students to explore a location outside of the school for its emergency preparedness and then report their findings back to the class.
