Splish-splash - and lots of screams.
It might look like weekend fun, but this is actually a school trip.
While these 4th graders from Buchanan, Breckinridge, Eagle Rock and Greenfield Elementary schools are having a good time, you can see from the looks on their faces they're engaged, and actually learning.
"We're going in the water and looking for bugs," explains Eagle Rock Elementary fourth grader Dylan Bulton.
"We were catching crawdads, fish, and other stuff," adds classmate Jacob Vanness.
"... go in the creek and to find all those icky stuff in the water like the rocks," laughs Breckinridge fourth grader Kahliiah Davis when asked her favorite part of the day.
While criss-crossing the creek resonates with most of these students, there are 5-stations that cover different parts of the Chesapeake Bay section of the Standards of Learning.
Each station has some hands-on aspect.
While this might seem like a day of fun with kids playing in the water and even getting dressed up- the hope is they'll learn lessons that will last a lifetime.
"What we really want kids to come away with today is even though they don't live by the water, some of them said they've never even been to the bay, that they're connected and what they do up here in the upper watershed, impacts those people down on the bay," explains Diana Hackenburg, Western Virginia Land Trust.
Tuesday's field trip was funded by a grant from the Chesapeake Bay Restoration Fund.
Fourth graders from the rest of the county's elementary schools will be heading to the field trip next week.
