Countdown to Mystery Class: Two Weeks to Go! | |||||||
Mystery Class is about to begin! Get ready to record your first sunrise/sunset times on Monday, February 1st. Then, on Friday, February 5th, we'll provide the first set of sunrise/sunset times from Mystery Sites around the globe. This final Countdown to Mystery Class is designed to prepare you for a special set of clues called the "Longitude Clues."

Teacher's Practice Packet #2: Discovering Longitude Clues | |||||||
As the spring equinox approaches, students will begin to explore information that will help them estimate where Mystery Classes are located east and west of the Prime Meridian. Using longitude clues that focus on sunrise times in Universal Time, students "do the math" to estimate longitude degrees for each Mystery Class. Through this hunt for longitude locations, students gain a greater understanding about the Earth’s daily and seasonal cycles. Teacher Practice Packet#2 includes background information that will help you understand the science and math behind longitude clues, student worksheets that give step-by-step instructions for working with longitude clues, sample worksheets to use for reference, and the map used for plotting the east/west locations of Mystery Classes. With the information and worksheets you will be able to:

Preparing Students: Exploring Words and Diagrams | |||||||
As you give each group an envelope, remind students that as they explore the contents (words and diagrams), you will be walking around and listening for “sleuth-speak,” where students are asking lots of questions about each item in the envelope. Use guiding questions to assist students' exploration:
Have students record a list of questions elicited by their exploration of the words and diagrams. Over the course of the season, revisit the diagrams and questions to assess students' understanding about the Earth's daily and seasonal cycles. Encourage students to draw their own diagrams to showcase their understanding. Post diagrams and word cards on a bulletin board or learning center to use for reference throughout your search for the Mystery Classes. |
