How Far Away Is Lightning Weather Science Experiment

In this fun and easy weather science experiment for kids, we’re going to learn how to determine how far away is lightning. 

 

Materials:

  • A thunderstorm




Instructions:

  1. During the next thunderstorm, wait in a safe indoor location for a flash of lightning.
  2. Once you see the flash of lightning, begin counting in seconds until your hear the sound of thunder.
  3. Every five seconds between the lightning flash and the thunder equates to you being roughly one mile away from the lightning.
  4. For instance, a ten second count would mean you are about two miles away from the lightning.
