      - Skills and values: Observe, describe, compare; handle materials safely and respect others’ observations.
    - - Key concept: Raw materials are changed through processes such as molding, drying, heating or crystallising.
      - Inquiry activity: Learners arrange picture cards showing the stages from sugarcane to sugar or clay to brick, predict what changes at each stage, and explain their reasoning.
      - Skills and values: Predict, sequence, explain; show curiosity and care when discussing materials.
