Rapid earth changes

CONCEPTUAL

Science›Space Systems & Earth's History|Ages 7—8|ID: mt_ZJu8s-Q1xa

Use information from several sources to provide evidence that Earth events can occur quickly (earthquakes, volcanic eruptions) or slowly (erosion, mountain building)

Mastery Evidence

Give at least two examples of rapid Earth events (earthquake, volcanic eruption, landslide, flood)
Give at least two examples of slow Earth processes (erosion, mountain formation, canyon carving)
Use evidence from text, images, or video to support the distinction between fast and slow changes

Assessment Prompt

“Can [child] give examples of things that change the Earth quickly, like an earthquake, and things that change it very slowly, like a river carving a valley?”

Preventing Erosion hard
Must understand erosion before comparing fast vs slow Earth events
- 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 knowledge supports understanding geological events
- 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
