Heating & Cooling Changes

CONCEPTUAL
Science›Matter & Materials|Ages 7—9|ID: mt_Pl-nsjYGZ3

Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius

Mastery Evidence

  • Describe melting (solid to liquid) and freezing (liquid to solid) with everyday examples
  • State that water freezes at 0°C and boils at 100°C
  • Explain that heating adds energy causing particles to move more, leading to state changes

Assessment Prompt

“Can [child] explain what happens to an ice cube when you heat it, and at what temperature water freezes and boils?”

Show full prerequisite tree
  • 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
