Discovering Photoperiod Clues
Teacher's Planning Packet #1
Packet #1 | Packet #2

During the spring Mystery Class season, the weekly photoperiod data your students receive will slowly reveal information about the latitude of the 10 Mystery site locations.

Teacher Practice Packet #1 includes the actual, start-to-finish sunrise/sunset data from a prior Mystery Class season. This practice packet will help you discover for yourself the relationships between latitude, sunlight, and seasonal change when you:

  • Practice calculating photoperiod.
  • Plot the data on a graph.
  • Examine the data to find patterns and surprises.
  • Make predictions and compare findings.
  • Reflect in your Mystery Class journal.

We hope the practice packet will give you a chance to experience the process of discovery your students will have when they begin to collect, organize, and analyze data to identify the locations of this year’s mystery classes.
