More Than a Shadow

"Where in the world do you think our 10 Mystery sites are located?"
No Hurt Feelings
So that Mr. Groundhog doesn't feel left out, you can still send a card to celebrate
his day:
Rise and Shine! Mystery Class Begins on Monday
Monday, February 5th is the first day of the Mystery Class project. Be sure to record the sunrise/sunset times for your hometown.
On Friday, February 9th we will post the first sunrise & sunset data for the mystery sites that are hiding around the globe. Over the next 11 weeks you'll be asked to unlock the secret of their locations.
To help you get started, take a look at the detailed Mystery Class information provided below, or see pp. 95-100 in the Teacher's Manual.
How to Participate in Mystery Class
Materials Needed:
- Mystery Class
Datasheet
- Mystery Class Graph
- YOUR Local sunrise and sunset times
Here's What You'll Do
1. Every Monday, between February 5 and April 16, record the time the sun
rises and sets in your hometown. Your local newspaper should provide this information,
or you may find it in a calendar from your area. Alternatively, look up sunrise/sunset
times on the WWW:
2. Calculate photoperiod by counting the number of hours and minutes the
sun is up. For example, if the sun rises at 6:50 a.m. and sets at 17:30 p.m., the
photoperiod for that day is 10 hours and 40 minutes.
3. Record the sunrise and sunset times and the photoperiod for each Monday
at your hometown on a Mystery
Class Datasheet. Then plot the photoperiod of your hometown on a Mystery
Class Graph.
Do NOT send your local sunrise & sunset data to Journey North!
4. Every Friday, we will post the sunrise and sunset data from our 10 Mystery
classes. Notice: The data you receive on FRIDAYS will have been collected on the
same MONDAYS your readings were collected. Many teachers divide their class into
10 groups, and give each group responsibility for a Mystery Site. To provide practice
for your student groups, use your local photoperiod as an example.
5. Make 10 copies of the Mystery Class Datasheet. Record the data from each
Mystery Class site on a separate Datasheet and calculate the photoperiod. Then plot
the photoperiod from each Mystery Class on your graph. Use a different colored pencil
for each Mystery Class. (You may want to make a large, poster-sized graph for your
class, where student groups could plot their respective sites.)
6. Beginning in March, clues about the geography and culture of each site
will be included with the weekly data reports. On April 27, 2001, students will race
to tell us where they think the 10 Mystery Classes are located.
7. May will be "Meet the Mystery Class Month". Each Mystery Class
will introduce themselves on-line and you'll have a chance to correspond with them....whoever
and wherever they are!
Have fun and good luck!
Teacher Tip--It Takes Teamwork!
Attempting to locate the Mystery Classes is one of the most integrated components of Journey North. Take a look at Wisconsin Teacher, and member of Journey North's Teacher-Advisory Board, Cathie Plaehn's suggestions for how to organize your class:
