Replicate one of Piaget’s conservation experiments. The easiest one is conservation of liquids (illustrated in Figure 5.4). Work with a child under age 5 who tells you that two identically shaped glasses contain the same amount of liquid. Then ask the child to carefully pour one glass of liquid into a taller, narrower glass. Ask the child which glass now contains more or if the glasses contain the same amount.
