Students investigate the interactions between land and water. Using
a stream table as their model, students observe how runoff causes stream formation; how
groundwater forms; how soil is eroded, transported, and deposited; and how water shapes
land. Students create hills, build dams, and grow vegetation. Miniature valleys,
waterfalls, and canyons form in the stream tables as water flows over the soil. Students
also deepen their appreciation for the vastness of stream systems by creating aerial
diagrams of their stream table results. The stream table also serves as a basis for
investigations of the water cycle. Through observing the model, manipulating certain parts
of it, and testing interactions under various conditions, students discover how water
changes the shape of land and how land formations, in turn, affect the flow of water. They
connect the models to real-world examples and apply the concepts they have learned to
photographs of land and water on earth. Through these applications, students are
encouraged to observe land and water each day and search for evidence of interactions
between land and water in the world around them.
