Students draw cross sections of a stream channel from field data. In the field, using a GPS, they determine the depth of a stream channel and use a spreadsheet to graph the stream channel.

Learners 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.

Young scholars investigate the relationship between upstream influences in their watershed and the watershed's estuary. They apply the scientific process to test a hypothesis while examining the impact of upland activities on estuaries.

Learners make a clay model and a geographic map of a watershed. They talk about the differences between the two representations and the potential human threats to watersheds.

Eighth graders examine the components of a watershed. They view overheads, discuss the hydrologic cycle, and observe a demonstration of a soil erosion box.

Seventh graders explore watersheds and take samples and analyze the data from a watershed in the area.

Pupils constrct a watershed and write about their observations. Students use maps to locate their area in relation to the watershed and inquire about what is applied to the ground above.

Students compile information about rainfall, lake elevations and releases of water from Tuttle Creek reservoir into maps, graphs and charts.

Learners read and analyze the story Away on the Bay as a springboard to discuss water pollution. They may look into ways in which water can be cleaned and a watershed restored.

Students define water basins and watersheds, then delineate the boundaries of their local water basin/shed using maps.

This inquiry is intended to provide students with practice developing investigable questions that need data, and specifically large datasets, to be answered. Click the teacher resources link for teaching guides and student handouts.

How can you learn to build your own watershed? This site features an activity to illustrate the basic properties of a watershed. Don't miss out.

In this lesson, learners will understand that water flows down a slope and determines how watersheds flow. They will also learn that water flows in three basic directions and that each watershed is divided by the area's higher elevations...
