With the addition of this week's data, does your Mystery Class chart look the way you expected? You'll find below the predictions from students who answered Challenge Question #28. We asked, "What do you think your graph will look like on March 22, 1996? Why do you think so?" Thanks to students in New York and Minnesota for some great answers.
Also included in today's report you'll find the first set of clues. Good luck as you search to find the answers--and the locations of our mystery friends.

Students Answer Challenge Question # 28:
"What do you think your graph will look like on March 22, 1996? Why do you think so?"
From MINNESOTA:
Dear Mrs. Berger's Class, We predict that on March 22, 1996
(actually, March 20), the lines on the graph will meet. March 20 is
the first day of spring, where everyone on the face of the earth
will receive 12 hours of day and 12 hours of night.
Thank you very much,

From NEW YORK:
Greetings from Ms. Babcock's fourth grade class in Elmont, LI, NY.
We think that on March 22, 1996 all the lines on our graph will
converge at 12 hours. We can see a pattern. If we were to continue
our lines in the direction they are now heading they would cross at
approximately March 20. During the Vernal Equinox (March 20) every
place on earth will have 12 hours of daylight and 12 hours of
darkness. The photoperiod in the Northern Hemishere will continue to
get longer, and the photoperiod in the Southern Hemisphere will
continue to get shorter until June 21. k12elbac@vaxc.hofstra.edu
From NEW YORK:
We think that all the graphs will be close to 12 hours of day light. We are
a bit confused by school #7. Is data for sunrise and set on 3/4 correct?
