Student groups use a specially engineered Lab-Aids© river model to investigate the dynamics of erosion and deposition of sediments. Students observe, describe, and interpret the erosional and depositional patterns created when "rain" falls over a non-level sand surface.

Common features created and described include: • stream channels • canyons • meanders • sand bars • deltas

They consider the role of gravity and the destructive and constructive nature of flowing water.

Accommodates two classes, each with 6 groups of four students.
