Curated OER
Salinity
Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.
Curated OER
Mud in the Water
Sixth graders investigate erosion. In this erosion lesson plan, 6th graders explore how farming changes the environment. Students construct an erosion model and research ways to protect the soil from excess mud generated by farming.
Curated OER
All Hands on Deck: A Harbor Education Program
Students build a model of an estuary. In this wetland activity, students build a model estuary with a paint tray and modeling clay. They use the model to illustrate the impact of non-point pollution on the watershed.
Curated OER
Gliding Glaciers
Students are introduced to the concept of glaciers. They discover how glaciers move and what types of landforms are formed by glaciers.
Curated OER
Water Pollution - Group Presentation
Students investigate water pollution at a web site and apply it toward a group presentation.
Curated OER
Sedimentary Rocks
High schoolers discover how sedimentary rocks form. They identify different examples of sedimentary rocks. They also discover what types of rocks are in Illinois soil.
Curated OER
Dark and Beautiful Caves
Students research how caves form. They describe the major stone formations in caves by taking notes. They construct a clay model of a cave and mark each formation making it easy to identify in the legend.
Curated OER
Rainy Day Hike
Students develop awareness about the water cycles. They identify the watershed in which their school is located. They explain the role the schoolyard plays in the watershed.
Curated OER
Mud in the Water
Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.
Curated OER
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
Watershed Island
Students 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.
Curated OER
Hydrologic Cycle
In this science worksheet, students examine the hydrological cycle through the coloring of the picture that graphically organizes the concept.
Curated OER
The Water Cycle
Students research the water cycle and identify main vocabulary associated with the water cycle. They build and observe a closed system model that demonstrates the water cycle in action.
Curated OER
Wetlands Project
Students discover how wetlands filter out contaminants before they can reach other bodies of water. In groups, they design and build a model of a stormwater wetland. They test the water quality and inform their classmates about the...
