About
Mystery Class
Using sunrise and sunset clues, students try to find the locations of
10 mystery class sites. Students discover that, while spring sweeps across
our Northern Hemisphere, day length is changing everywhere on earth. Students
must use reasoning, graphing, and research skills to pinpoint exact locations
of the mystery classes. During their search, students also discover the
reasons for seasons.
