Students from Nardi Routten’s fourth grade class at F.K. Sweet Elementary recently enjoyed an unique learning experience at Blind Creek Park. Students rotated through four different activities: seining, beach clean-up, water testing, and mangrove planting/measuring. Jennifer Fleschner, a parent volunteer helped Jason Moore and Annamarie Brosnihan test the river water for oxygen levels. The students concluded that the deeper the water level, the higher the oxygen levels.
