Curated OER
Marine & Aquatic Habitats -- Journey of a Drop of Water Through a Watershed
Learners discuss pollution and the steps in the hydrologic cycle. They follow a drop of water through a watershed simulation. They discover the components of a water cleaning system as well.

Underwater Picture of the Hudson River Estuary
Young scholars identify important aspects of water quality such as slainity and turbidity. They test two of the water quality parameters and determine the quality of the water. In addition, they construct two sets of graphs based on data...
Curated OER
Technology as a Tool of Science
Students monitor streams, take stream surveys, collect chemical and macro-invertebrate and stream discharge data. Using a digital camera, students observe the percentage of various types of vegetation on the flood plan, riparian area and...

"Pennsylvania Watersheds, Many Ways to the Sea"
Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.
