been chirping for a month. Osprey have returned
from Central and South America. And CBF
educators have emerged from the winter season
of preparation and planning ready to engage
students, teachers, and principals.
Pennsylvania creeks are ideal for spring
exploration to get a preliminary look at water quality.
Armed with waders to brave the chilly water,
students on our Susquehanna Watershed
Education Program (SWEP) test the water to help
determine the health of local watersheds.
CBF’s Senior Naturalist in Virginia, Bill Portlock,
came upon this spotted turtle (clemmys guttata)
on a bridge crossing the Mattaponi River in Caroline
County. A sure sign of spring, the spotted turtles
emerge from winter hibernation in mid-March.
Students on CBF education programs frequently
encounter many types of turtles, but spotted turtles
are rarer and their presence is a welcome indicator
of a healthy environment.
Students from KIPP DC Heights Academy learn
how to use CBF’s new water quality app to share
the data that they collected on the Potomac River.
CBF’s Sam Woolford, one of the project leaders,
shows students how to use a mobile device to
enter the readings for dissolved oxygen, nutrients,
pH, and turbidity so they can continue to see how
everyone’s actions are connected to water quality
when they return to the classroom. 19
