During Weeks 1-6:
I started by learning how to use the ______/______ times to calculate the ______ at each site. Then I graphed the week-to-week changes in ______ at each Mystery Class, and at my own location too.
Locations whose photoperiod ______ were in the ______ Hemisphere, while those whose photoperiod ______ were in the ______. Locations whose photoperiod changed very little were near the ______. A location's north/south position relates to the ______ part of its global address.
I narrowed my search by comparing each location's photoperiod to photoperiod at ______ location, which told me if a Mystery Class was ______ or ______ of me. After graphing and tracking the Mystery Classes for several weeks, I was also able to put them in order from ______to ______.
I discovered that I knew a lot about the ______ of the Mystery Classes, but I still didn't know anything about their ______. This is because tracking the changes in ______ does not tell you anything about ______.
During Week 7:
I finally learned how to estimate the ______ of the Mystery Classes by calculating the amount of time that passed on March _____ between ______ at ______ and sunrise at a specific Mystery Class using UT. I then converted that amount of time into ______, and divided that number by _____ to learn how many ______ away from Greenwich a specific Mystery Class was. Then I looked at the specific Mystery Class's UT sunrise time to see if it was before or after the UT sunrise time at Greenwich, and that told me if it was _____ or _____ . This calculation only worked on that date, the vernal ______ .
During Weeks 8 – 11:
I zeroed in on each Mystery Class with clues about their ______, ______, ______/______, and finally ______.
