According to Piaget's theory, the term conservation means which of these?

• A. The idea that color determines shape
• B. The idea that shapes can transform into other shapes
• C. The idea that amounts/numbers are the same regardless of shape or appearance
• D. The idea that objects disappear when hidden

Answer: (C)

Conservation in Piaget’s theory is the understanding that the amount, number, or other quantitative property of a substance stays the same even when its appearance changes. So, the same amount of liquid remains the same when poured into a tall, thin glass or a short, wide one, and the same number of items remains the same even if they’re rearranged. This capacity develops as children move from preoperational to concrete operational thinking, where they begin to consider multiple aspects of a situation rather than focusing on just one perceptual feature like height. Younger children often think the taller glass has more liquid because they tend to center on a single dimension and haven’t yet grasped invariance or reversibility. The other ideas describe different concepts (perceiving color as determining shape, transforming shapes, or understanding that objects exist even when not seen) and do not capture the idea that quantity stays constant despite changes in appearance.
