Discussion
of CQ #2: The Plot Thickens--What Happened to Class #9?
Speaking of data, last week's sunrise/sunset data for MC #9 had such a sudden
and unusual one-hour change, that it made one class write to double check:
"Are
the times correct for class #9 for the week of Feb. 20?" That sudden
data shift was exactly the topic of Challenge Question #2.
Did you figure
out what happened to Class #9?
Converging
or Diverging?
After
you've plotted today's fifth set of data, what do your graph lines reveal?
Can you determine whether the photoperiods for the ten secret sites are
coming together or growing apart? And what does this mean?
Study your graph carefully, and then try to answer these questions:
Challenge
Question #3:
"Look at your graph and think about what you have discovered about
sunlight and seasons in your hometown and at Mystery Class #4. What
type of weather changes do you think Mystery Class #4 might be experiencing
right now? How does that compare to your hometown weather?"
Challenge
Question #4:
"Can you predict what your graph will look like on March 20, 2006,
the Vernal Equinox? Why do you think so?"

Longitude
Clues Coming Next Week
In
next week's Update, we'll provide the long-awaited Longitude Clues and
instructions. These clues relate to the upcoming Vernal Equinox, and they
will be amazing. Why? Because they will help you estimate the APPROXIMATE
Longitude of the Mystery Classes, and get you closer to discovering where
they are hiding. But how does this work?
