Students will:

  1. Describe the factors that influence the salinity of the bayou.

  2. Explain why estuarine habitats are important.

  3. Test the water quality of the bayou using scientific equipment.

  4. Examine animals found in and along the bayou.

  5. List human-made stresses that threaten the balance of the bayou ecosystem.

  6. Practice observation skills.


  • Bayou - a channel of water that flows slowly in both directions, depending on the tide and wind

  • Brackish water - a mixture of salt and fresh water

  • Diversity - variety of species in a given area

  • Estuary - regions of interaction between rivers and near-shore ocean waters, were tidal action and river flow create a mixing of fresh and salt water

  • Ecosystem - An ecosystem is a complex, dynamic system that functions as a whole. An ecosystem is a natural unit and its size can be as small as a drop of water or as large as the Earth. Ecosystems consist of the interactions between organisms and between organisms and physical components, in which materials are exchanged following closed paths.

  • Salinity - salt content of water

  • Turbidity - measure of the clarity of water; how much turbulence or activity (tides, wind, etc.)
