In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.
Water Body Salinities IAdd to list Details
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
Water Body Salinities IIAdd to list Details
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Test Density with a Supersaturated Solution
Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.
EstuariesAdd to list Details
An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.
Nutrients in an EstuaryAdd to list Details
In this activity, learners model estuaries, artificially enriching both fresh and salt water samples with different amounts of nutrients and observing the growth of algae over several weeks.
Human Impact on Estuaries: A Terrible Spill in Grand BayAdd to list Details
In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
Amphipods: More than Mud
In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.
A Hurricane's Storm Surge Affects our Estuaries
In this activity, learners construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.
