NOTE TO TEACHERS: Students sometimes focus heavily on "winning" the Mystery class contest, so please be sure to remind them that the contest portion is only a small part of this Activity. Also, we are aware that there is a wide range of grade levels participating, and we will factor that in during the judging.

"We bid a fond farewell to our Mystery sites as the sun sinks slowly into the west," said Mrs. Berger's class as they submitted the last set of sunrise/sunset data for the season. Hats off to them for the terrific job! If you'd like to drop a note of thanks, you can reach them at:
K12robzj@hofstra.edu or jberger@dorsai.org

Here is the Final Sunrise/Sunset data for this week, and you'll also find another set of clues below, which are the final clues of the contest--good luck!!
