During which stage do children begin to think logically about concrete objects and understand conservation?

• A. Sensorimotor period
• B. Preoperational period
• C. Concrete Operations period
• D. Formal Operations period

Answer: (C)

In Piaget’s theory, the ability to think logically about concrete objects and to understand conservation appears in the concrete operational stage, roughly ages 7 to 11. At this point children move from relying on appearances to performing mental operations on real, tangible things. They understand that quantity stays the same even if the form changes—for example, pouring water into a differently shaped container doesn’t change the amount of water—showing conservation. They also develop reversibility (recognizing that actions can be undone in the mind) and decentration (considering multiple aspects of a problem rather than just one perceptual feature). Earlier stages lack these logical operations on concrete objects, while the next stage adds abstract reasoning beyond the concrete.
