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 thunderstormA 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
