Sometimes as a border between preoperational period and concrete-operational period Piaget suggested **conservation experiments**. For example, two equal glasses filled with liquid are presented to a child, after which liquid out of one glass is poured into a third, more narrow glass. The child is then asked which glass holds more liquid. Only a child in the concrete- or formal-operational period should realize both glasses hold equal amount of liquid. | Sometimes as a border between preoperational period and concrete-operational period Piaget suggested **conservation experiments**.
