Severe Weather

 
Have you ever planned an outdoor party or activity, and it was ruined by bad weather? We all have. These are some types of severe weather: hurricanes, tornados, thunderstorms, and rainstorms. Some could spoil a picnic, while others could destroy lives and property. 
 
  • Hurricanes are storms formed over warm oceans. Hurricane winds are at least 75 miles per hour(mph), but can be much higher. These storms can be many miles wide.
  • Tornados are whirlpools of wind that form over land. Winds can be as much as 300 mph. A tornado's path can cover several miles. It isn’t as wide as a hurricane, and usually covers an area less than 100 yards.
  • Thunderstorms have a mixture of rain, high winds, dark clouds, thunder and lightning.
  • Rainstorms have dark clouds, rain showers, and breezes.
 
TRY IT
 
Ask your teacher if you can create the sound of a storm in your classroom. Turn off the lights, and have everyone tap one finger on their desk. This is rain. Tap all your fingers on the desk so it "rains" harder. Have someone turn the lights on and off quickly to represent the lightning. Add snapping fingers and stomping feet as the "storm" gets worse. Finally, repeat the sounds more quietly in reverse order as the storm passes over.
