DATA FROM THE MYSTERY CLASSES: Q: When and how will the sunrise/sunset data from the Mystery Classes be given each week?
Every Monday during the Mystery Class activity, students will record their local sunrise and sunset times on their Data Sheets. Using this information they will calculate daylength (photoperiod) in their hometown. On the same days, students at ten secret Mystery Class locations around the world will also record their own local sunrise and sunset data. Then, on Friday of each week, the data from the secret Mystery Classes will be posted in the weekly Friday Update.
