Sci-Doku.  To complete this puzzle, you need to use the numbers 1-5 one time only in each row and column.  You are allowed to research to solve the clues.  This is due by May 4th .  Responses can be printed off and handed-in, or they can be emailed to me.  Note, if you choose to email the responses, please check with me to be sure that I received them.  Thanks!
