Use your math skills to estimate the distance of a thunderstorm. Since light travels much faster than sound you will see the lightning before you hear the thunder.
Step 1: Begin by pressing START. After the lightning
flashes, look at the stopwatch to see how many seconds have passed.
For every five seconds, the lightning is approximately one mile
away - it's as easy as counting by 5's.
Step 2: Turn off the stopwatch. Count the seconds to yourself as "one one-thousand, two one-thousand, three one-thousand" etc.
Step 3: For a challenge, switch to the advanced mode. In this mode, you will encounter decimals. Each second is approximately equal to .2 miles. Multiply the number of seconds by .2 to determine the distance in miles.
