• How Far Away Is That Storm?
• The purpose of this experiment is to watch
  lightning and hear thunder to give you clues
  about how far away you are from a storm.
• One thunderstorm
• A stop watch (or the ability to say
  "one-Mississippi")
• 1. After you see a flash of lightning, count the
  number of seconds until you hear the thunder.
  (Use the stop watch or count "One-Mississippi,
  Two-Mississippi, Three-Mississippi," etc.)
• 2. For every 5 seconds the storm is one mile
  away. Divide the number of seconds you count by 5
  to get the number of miles.
• What travels more quickly, light or sound?
• If you said light travels faster than sound,
  you're right! The lightning and thunder are
  happening at the same time, but light reaches you
  instantly, while sound takes longer.
• Do you ever see lightning without hearing
  thunder? Some call that "heat lightning," but it
  is really lightning that is over 15 miles away
  and too far away for you to hear the thunder!
• LOOK OUT if you see the lightning and hear the
  thunder at the same time
