Welcome, Let the Games Begin!
It's here at last. Thousands of people are coming together this week, in the spirit of global peace and friendly competition. The international champions have been warming up all week, double-checking their equipment, and going over their strategy with coaches and teammates. We must be talking about the Winter Olympics in Torino, Italy, right?
Wrong. We're actually talking about another international competition, the 2006 Mystery Class contest. You're the competitors, and today is the opening ceremony. Welcome to Mystery Class.
Although you won't see the ten secret classes parading around a stadium, you will start to learn something about each site. Today they're each revealing some unique data that sets one apart from the other. And they're eager to have you get started. Warm-ups are officially over--Watch the video and "Let the Games Begin!"

First Greetings from Your Secret Mystery Friends
"Hi Everyone--Here we go! Everyone is JAZZED here. Being a secret Mystery Class is BIG STUFF--kids and parents are equally excited here. And we're eager for you to find us. Good luck! Sincerely, Mystery Class #3"
Did you record your hometown sunrise/sunset times on Monday? Good job. Now let's get focused on the first set of unique data from each of your undercover mystery friends--THEIR sunrise/sunset times, which are posted in today's Update. Even though the 10 sites are vastly different, they all have one central "clue" in common--the fact that the amount of sunlight is changing at each location. As spring sweeps across the Northern Hemisphere, day length changes everywhere on Earth. So "follow the sun" and discover the secret sites.
Once you collect their data below, you'll need to figure out each location's day length (photoperiod) from its sunrise/sunset data. Take a look at these suggestions:
* "Kids Calculating Photoperiod":
http://www.learner.org/jnorth/tm/mclass/KidsCalculatingPhoto period.html
* Teacher Tips on Photoperiod:
http://www.learner.org/jnorth/tm/tips/#MC
In the coming weeks, we'll continue to provide their sunrise/sunset times, and later in the season we'll also "leak" a few clues from them too. (They'd love to tell you where they are, but for now their lips are sealed!)
Don't forget to record the Mystery Classes' sunrise/sunset data on your Datasheets, and use the Graphs to chart their photoperiod too. Teachers, you may want to divide your class into 10 groups. These materials can be found here:
