This video shows how plants help anchor the soil and prevent erosion.
How Plants Anchor Soil (PDF) Lesson Plan
1. Is erosion a bad thing?
2. How would you define erosion?
3. Why is dirt important?
4. Why do we want to keep dirt where it is?
5. What stops erosion?
4-ESS2-1 Earth's Systems
Students who demonstrate understanding can: Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.
Disciplinary Core Ideas
ESS2.A: Earth Materials and Systems
Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, living organisms, and gravity breaks rocks, soils and sediments into smaller particles and move them around
Living things affect the physical characteristics of their regions.
Crosscutting Concepts: Cause and Effect
Cause and effect relationships are routinely identified, tested, and used to explain change.
Science and Engineering Practices: Planning and Carrying Out Investigations
Planning and carrying out investigations to answer questions or text solutions to problems in 3-5 builds on K-2 experiences and progresses to include investigations that control variables and provide evidence to support explanations or design solutions. Make observations and/or measurements to produce data to serve as the basis for evidence for an explanation of a phenomena.
