How Thunderstorms Form

  • Moisture rises and forms a cloud
  • When a cloud is full, it releases moisture in the form of rain drops
  • Droplets in the clouds each have a different charge: positive and negative
  • Different charged droplets are attracted to one another and begin moving toward each other
  • The moving droplets bump and cause static electricity, which creates a spark we see as lightning
  • Lightning can spark from one place in a cloud to another place in the same cloud; from one cloud to another cloud; and from a cloud to the ground

Good Things About Lightning

  1. it puts back nitrogen into the soil
  2. it causes forest fires, which are needed so new trees can grow
  3. it splits open the seed pods of the Sequoia tree, so young trees can sprout
My Science Fair Project

My project was about Thunder & Lightning Storms

What to Do

If You're Outside in a Storm
  • Get away from trees and tall things. Stay away from hilltops, benches and open fields. Find low places for shelter, like ditches
  • Crouch : bend over, hands on knees, keep as little of your body on the ground as you can. Keep head off ground
  • If with a group spread out
  • Stay away from water

Storm Facts

  • Since warm temperatures are needed for thunderstorms, places close to the Equator have more.
  • The island of Java has thunderstorms 223 days of the year.
  • Lightning strikes the earth between 8 and 10 million times a day.
  • The Pacific Coast of the U.S. doesn't get many thunderstorms because air is dry and cool.
  • A bolt of lightning is actually one "leader" coming from a cloud, and another "leader" coming from the earth. They meet to form what looks like one bolt.

Create a Cloud!

  1. Boil water in a tea pot
  2. Hold a metal bowl of ice over the steam
  3. Look under the bowl to see a cloud
