Seasons of the Estuary Biome 

Estuaries and the lands surrounding them are places of transition from land to sea and from freshwater to salt water. Estuaries are protected from the full force of ocean waves, winds, and storms by the reefs, barrier islands, or fingers of land, mud, or sand that define an estuary’s seaward boundary. This title will allow students to develop a model to represent the estuary biome, including the shapes and kinds of land and bodies of water in such an area.
