What happens when things collide

CONCEPTUAL
Science›Energy|Ages 9—10|ID: mt_1MLi55bPnt

Ask questions and predict outcomes about the changes in energy that occur when objects collide

Mastery Evidence

  • Predict the outcome of a collision based on the speeds and sizes of the objects
  • Explain that energy transfers from one object to another during a collision
  • Describe observable changes: one object speeds up, the other slows down, sound is produced

Assessment Prompt

“If [child] rolls two balls towards each other, can they predict what will happen when they hit and explain that energy transfers between them?”

Show full prerequisite tree
  • Speed and energy hard

    Must relate speed to energy before predicting energy changes in collisions

    • Naming types of energy hard

      Relating an object's speed to its energy requires 'kinetic energy' vocabulary

    • Pushes & Pulls hard

      Must understand forces change motion before relating speed to energy

      • Drawing Force Diagrams soft

        Understanding pushes and pulls as forces is supported by the arrow representation of magnitude and direction
