Overall health is very dependent on a good night's sleep.  In our third session of the year, we focussed our attention on the Health topic of sleep.  We learned how the natural day/night cycles and seasonal cycles are made in the solar system.  We learned about the history of sleep, the biology of sleep, and how other animals sleep similarly or differently compared to humans.  We also talked about how sleep needs change over the life span. In music classes we learned a winter lullaby.  For our culminating activity the students wrote and produced a news cast about sleep complete with an interview with Sand Man, an investigative report, commercials, and a play-by-play of the stages of sleep.
