Students explore the marsh to learn about food webs

Students explore the marsh and learn about food webs, habitat and ecosystems



Using seines and dip nets, students spend 1 hour collecting marine organisms, viewing and identifying marsh creatures and enhancing their understanding of salt marsh ecosystems.

Students begin with an orientation to the marsh, beginning with the producers and microorganisms. Students then work their way up the food chain viewing the primary consumers like the filter feeding mussels, shrimp and comb jellies. Students use nets to catch fish and crabs and discuss the flow of enegy from the marsh to their dinner table.

Students need footware and cloths appropriate for "marsh mucking". A change of cloths and a towel are recommended.
