Taking Apart & Rebuilding

Science · Matter & Materials · conceptual

Observe that an object made of a small set of pieces can be disassembled and made into a new object, understanding that the pieces still exist

Sign in to track this

What mastery looks like

  • Explain that taking apart an object and rebuilding it uses the same pieces in a new arrangement
  • Describe how the pieces themselves don't change even though the object looks different
  • Give an everyday example of reusing materials to make something new

Check your understanding

If Taking Apart & Rebuilding builds a tower with building bricks and then takes it apart to build a car, can they explain that the same bricks are used but arranged differently?
