On July 14, 2016, FODM hosted 25 George Washington Middle School students participating in the Alexandria Public Schools’ summer STEM (science, technology, engineering and mathematics) program and two of their teachers.  The students learned about the natural resources of Dyke Marsh and conducted some water testing using seine nets. 

They found minnows and determined the water’s temperature, salinity, acidity and alkalinity (pH).  The lead teacher, Emmet Rosenfeld (pictured), is also Director of Programs for the George Washington Memorial Parkway Trust.  The Trust’s president, Mari Lou Livingood, also attended.
