Estuary Food Webs: Links for Teachers
Estuaries 101: Survival in an Estuary
In this activity, students investigate the range of conditions that animal and plant species need to survive in an estuary. They examine data for abiotic factors that affect life in estuaries - salinity, dissolved oxygen, temperature, and pH. Students use archived data (trend analysis graphs) and real-time conditions at Elkhorn Slough to predict whether a particular animal or plant species could survive in an estuary.
