Effects of the Southern Pacific Railroad Causeway

Fifth graders describe the appearance of a substance before and after a physical change. They re-create the Southern Pacific Railroad Causeway across the Great Salt Lake. They determine for themselves how the water is exchanged between the north and south arms of the lake, how the saline settles due to its density, and how the volume of the water in the south arm controls the flow or exchange of waters between both arms.
