Hi!
We are 4th and 5 th graders from Columbia Elementary School
located in Annandale, VA. It is snowing 10" of snow today
and we are off from school. We are collecting photoperiod
and daily temperature ranges. Are you interested?
We can be reached at cgrafiel@osf1.gmu.edu Brassard.Candace@epamail.epa.gov
Please use both addresses since this is a team effort.
Thank you.
