Lab-Aids: Modeling Stream Erosion and Deposition Kit

Lab-Aids: Modeling Stream Erosion and Deposition Kit

• Grades: 6-8+
• Number of Students: Consumables service 48 students (2 classes, each with 6 groups of 4 students)
• Number of Lessons: 1 Activity
• Contact Hours: 1-2 ~50 minute class periods
  

Highlights:

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

Curriculum or Lesson Topics:

Scientific Concepts

• Landforms are the result of a combination of destructive forces (such as erosion) and constructive forces (such as deposition).
• Gravity transports water and earth materials over Earth’s surface where it collects in rivers, lakes, and oceans.

Key Vocabulary: delta, deposit/deposition, erode/erosion, sediments
