I was looking out my window watching the snow fall this weekend.  Did you know that no two snowflakes are the same?  Also, all snowflakes (or ice crystals) have six sides.  If the snow fell at a rate of 3 inches per hour, how long would it take until we would have 2 feet of snow?
 
 
 
 
 
 

Design your own snowflake - remember that it must have 6 sides and be symmetric (the same on both sides).
