Modeling Stream Erosion and Deposition
kit #442
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.
- Gravity transports water and earth materials over Earth's surface where it collects in rivers, lakes, and oceans
- Landforms are the result of a combination of destructive forces (such as erosion) and constructive forces (such as deposition) of sediments
