Mystery Class Update: March 2, 2007

Today's Report Includes:

This Week's
Sunrise/Sunset Data
for Monday Feb 26 >>

Journal Questions: Converging or Diverging?
After you've plotted today's fifth set of data, what do you think your graph lines will reveal? Are the photoperiod lines coming together or growing apart? What does this indicate? Study your graph, and then try to answer these questions in a journal:
  • Prediction: Can you predict what your graph will look like on March 21, 2007, the vernal equinox? Why do you think so?

  • Compare & Contrast: What have you discovered from your graph about changes in sunlight and seasons at your hometown as compared to Mystery Class #10? What type of weather changes are being experienced at these two locations?
Time Out
Are you paying careful attention to the sunrise/sunset times each week, as well as the photoperiod? Study MC #7's times this week. What do you notice? What caused this to happen? Why doesn't this change the photoperiod trend line on your graph?
