We may try and do the Mystery Class this year. I learned about this from Alex over at Canadian Home Learning a couple of years ago. I have watched through her blog how much her children enjoyed this clallenge. Basically, from what I understand, there are ten cities around the world. These cities document their sun rise and sun set over a period of time. The participants in this challenge document each city and their own sun rise and sun set and when the time period is finished they compare them all and research it to try and make an educated guess as to which cities the mystery locations are. It starts January 30th so click HERE to learn more or register for Mystery Class.
