Play With Thunder

If there's a thunderstorm try these:
  • Time how long between a lightning flash and the thunder and multiply that by sound's speed per second - and you'll know how far away each lightning was.
  • Using a decibel app, measure how loud the thunder is.
  • Keep recording the distances, and loudness, and plot them. You could figure out the speed the storm is moving.
  • Look up 'thunder' in the Bible - see what you find.
