Taking Apart & Rebuilding
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
Suggested ages 7–8
Learning journey
Your child is investigating how materials behave — classifying substances by their properties, understanding why different materials are used for specific purposes, and exploring how heating and cooling can change materials.
Evidence of understanding
- 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
Assessment prompt
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?
