Conservation in the Preoperational Stage
Conservation is the principle that an object's quantity or properties, such as size or volume, remain the same despite changes in its appearance, provided nothing is added or removed. A child's understanding of this concept is evaluated using Piaget's conservation tasks. Children in the preoperational stage typically have not yet developed this understanding.

A researcher shows a 4-year-old two identical, short glasses, each containing the same amount of juice. The child agrees that both glasses have the same amount. The researcher then pours the juice from one of the short glasses into a tall, narrow glass. The juice level in the tall glass is now visibly higher than in the remaining short glass. If the child has not yet developed the understanding that an object's quantity remains the same despite changes in its appearance, what will they most likely conclude?
An adult shows a 4-year-old child two identical, short, wide glasses, each filled with the same amount of water. The adult then pours the water from one of these glasses into a tall, thin glass. The water level in the tall, thin glass is now higher than in the short, wide glass. If the child is asked which glass has more water, what will the child most likely say?
