Last week the students in Mrs. Biewald's class were worried
that our friends at Mystery School #3 had too much sunlight
to sleep. From the looks of today's sunrise and sunset data,
their problems may finally be over.

If you're worried that you'll NEVER figure out where these
Mystery Classes are located, here's a suggestion:  Graph the
RATE photoperiod changes at each location and compare it
against the rate of change at the only known location--your
own.  Here's how:

1)  Divide your class into 12 groups.

2)  Have each group chose one of the 11 Mystery Classes and
    have one group chose your own class.

3)  Your goal is to make a graph that will show the number
    of minutes lost or gained at each location each week.
    Hold a classroom discussion and decide the scale that
    would work for your graph.

4)  Each week as yourself these questions:  At which sites
    is the photoperiod increasing?  Decreasing?  What does
    this tell me about each location?  At which locations
    is photoperod changing the fastest?  Where is it changing
    the least?  What does the RATE of change tell me about the
    location of each class?

Remember, on the first day of spring we'll begin to send
some clues!

WRITE ABOUT IT!

Have you noticed that the days are getting longer where you
live?  Write a poem that captures the feelings that come
with this sign of spring.  Please include the many changes
you observe in nature at this time of year where you live.

Send your poem to:  jnorth@informns.k12.mn.us   On the first
day of spring we'll share all the poems we've received with
everyone.
