Play “Mystery Class”. Use sunrise and sunset times to find 10 mystery classrooms located all around the world. Each Thursday new clues are shared. The first clues came out last week and today the second of 11 sets of clues were shared.
Here’s an example from Mystery Class #4 “No sunset here, it's all daylight all the time ... at least for now.”
