What is an Estuary?
Young scholars 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
Along Our Coast
Students explore the coast lines of Florida. They examine the benefits of estuaries and examine the estuary systems found along the coast. Students research and construct a saltwater food web.
Curated OER
Salinity and Brackish Water Systems
Students are able to tell the difference between brackish and salt water. They also are able to distinguish water qualities specific to each type of water. Students answer various questions about all types of water.
Curated OER
Sink or Float?
Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.
