What is an Estuary?
Students define the terms estuary and watershed. They conduct an experiment to determine the density differences between fresh and saltwater. They examine the salinity distribution of the Peconic Bay Estuary.
Curated OER
Water Quality
Students examine the YSI and the water properties that it measures. They identify the different properties of water pH, DO, temperature, turbidity, and salinity and determine why it is important for them to test these parameters.

Freshwater Habitats
Students take samples from local freshwater sources and examine them for macroinvertebrate life. They take samples from both shallow and deep freshwater environments, measure temperatures, and classify organisms found in their samples.
Curated OER
Aquatic Organisms and Their Habitats
Learners investigate the presence of specific organisms in a freshwater habitat to determine the quality of that habitat. They conduct a field study and distinguish and classify organisms found during the field study.
