Erosion and weathering

PROCEDURAL

Science›Earth's Systems|Ages 9—10|ID: mt_vAP_A986IQ

Make observations and measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation

Mastery Evidence

Define weathering (breaking down of rock in place) and erosion (movement of broken rock/soil)
Describe the effects of at least three agents of weathering/erosion: water, ice, wind, vegetation
Provide evidence from observations showing how weathering or erosion has changed a landscape

“Can [child] look at a crumbling cliff or a river bank and explain how water, wind, or ice has slowly worn away the rock or soil over time?”

Types of rocks hard
Measuring weathering and erosion rates requires 'weathering', 'erosion', and 'deposition' vocabulary
Preventing Erosion hard
Must understand erosion prevention before measuring weathering/erosion effects systematically
- 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
Properties of materials soft
Rock properties knowledge supports understanding how weathering breaks down different rocks
- Grouping Materials soft
  Grouping materials by properties supports grouping rocks by properties
  - Describing Material Properties hard
    Must describe properties before using them to group materials
    - States of Matter Vocabulary soft
      Describing physical properties of materials uses solid/liquid/gas vocabulary introduced in the states of matter LANGUAGE node
    - Naming Everyday Materials hard
      Must name materials before describing their properties
      - Objects vs Materials hard
        Must distinguish objects from materials before naming specific materials
