On the school-wide boat trip with the Department of Natural Resources September 17, students saw a demonstration of how pollution run-off can affect our rivers and estuaries.  They practiced scientific measurement by measuring the temperature, salinity and clarity of the water in a pond at Hobcaw.  Students used microscopes to view microorganisms in the water.  Then everyone got into the DNR boat for a trip around Winyah Bay, where they caught and identified several species of juvenile fish, then took the same water measurements in the estuary.  “My favorite part of the day was seeing three bald eagles soaring over the bay,” said Dr. Gary Gates.  Thanks to the DNR, staff at Hobcaw and Dr. Michelle Neubauer for organizing the trip.
