Which principle states that some physical attributes of objects remain the same despite changes in appearance or arrangement?

• A. conservation
• B. classification
• C. puberty
• D. initiative v. guilt stage

Answer: (A)

Conservation is the idea that some physical attributes stay the same even when appearance or arrangement changes. For example, the amount of water remains the same when poured from a tall, thin glass into a short, wide one, even though the glasses look different. The same principle applies to number or mass—rearranging objects or altering their shape doesn’t change the underlying quantity. This concept is central to understanding how people develop logical thinking, recognizing invariants despite surface changes. The other options don’t capture this idea: classification is about grouping by shared features; puberty refers to biological maturity; initiative vs guilt is a psychosocial stage concerned with personal and social development.
