Preventing Erosion

PROCEDURAL

Science›Earth's Systems|Ages 7—8|ID: mt_m6UaSmrQVG

Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land

Mastery Evidence

Describe how wind and water can change the shape of land (erosion)
Compare at least two design solutions for reducing erosion (e.g. retaining walls, plants, windbreaks)
Evaluate which solution works best based on evidence from tests or observations

Assessment Prompt

“If [child] sees a sandcastle being washed away by waves, can they think of ways to protect it — like building a wall or planting grass to hold the sand?”

Shapes of land and water hard
Must know about landforms before designing solutions to prevent wind/water erosion
- Seasonal changes soft
  Seasonal observation supports understanding land and water features
  - Days, Weeks, Months & Years soft
    Observing and describing seasonal changes requires basic date and time vocabulary (months, seasons, year)
    - Ordering Events in Time hard
      Understanding days/months/years builds on sequencing events chronologically
