The concept of conservation refers to the understanding that even if the appearance of an object changes, its fundamental properties (such as volume or amount) remain the same. In this case, the niece and nephew lack the mental ability to conserve the amount of milk they were given, which leads them to believe that one glass has more milk than the other.
