Where water is found on Earth

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

Identify where water is found on Earth and understand that water can exist as solid (ice) or liquid, recognising water in oceans, rivers, glaciers, and underground

Mastery Evidence

  • List where water is found on Earth: oceans, rivers, lakes, glaciers, underground, atmosphere
  • Explain that water exists as liquid (rivers, oceans) and solid (ice, glaciers, snow)
  • Recognise that most of Earth's water is in the oceans

Assessment Prompt

“Can [child] name the different places water is found on Earth — in oceans, rivers, ice caps, and even underground — and explain that ice is just frozen water?”

Show full prerequisite tree
  • Shapes of land and water hard

    Must know land and water features before learning where water is found on Earth

    • Seasonal changes soft

      Seasonal observation supports understanding land and water features

  • Heating & Cooling Changes soft

    Understanding state changes supports knowing water as solid (ice) and liquid

    • States of Matter Vocabulary hard

      Describing and measuring changes of state requires solid/liquid/gas vocabulary and the term 'change of state'

    • Drawing Particle Diagrams hard

      Observing and describing change of state requires reading particle diagrams showing how arrangement changes on heating or cooling
