What term describes the cognitive ability to understand that quantity remains the same despite changes in appearance?

• A. Conservation
• B. Reversibility
• C. Centration
• D. Irreversibility

Answer: (A)

Conservation is the ability to understand that quantity stays the same even when its appearance changes. For example, when the same amount of juice is poured into glasses of different shapes, a child who understands conservation recognizes that the amount hasn’t increased or decreased, even though the height or look of the liquid differs. This concept reflects understanding invariants across transformations, a hallmark of developing logical thinking in the concrete operational stage. Reversibility is about knowing you can undo a change by reversing the steps, centration is focusing on one feature (like height) while ignoring others, and irreversibility is not grasping how to reverse a change.
