Piaget’s theory is a comprehensive theory about how children’s brain develops. His theory includes Sensorimotor, Preoperational, Concrete Operational and Formal Operational stages. The Sensorimotor stage occurs between 0-2 infancy, ages when the child begins to interact with the environment (Berk, 2014). The Preoperational stage happens between ages 2-7 in early childhood is when children begin to think more reasonably (Berk, 2014) and begin to put objects into words. An example of this would be children playing make believe. The next stage is Concrete Operational which is between age 7-11 middle childhood where kids think more logically (Berk, 2014). The final stage of Piaget’s theory is Formal Operational is age 11 and up is when their reasoning …show more content…
Conservation is when you change the shape but, you do not change the amount of the object (Berk , 2014). My hypothesis is that the 9- year- old will not be able to conserve because her reasoning has not been fully developed. The first experiment involved the 9 year girl and I began by setting up two cups of juice. I then asked the 9 year old if there is the same amount of juice in each cup. The 9 -year -old responded with, “The longer container has more juice because the container is taller and wider”. Next I did the experiment with the 13-year-old girl. The 13-year-old stated that both cups are equal because she did not see me change the amount of juice. She uses reasoning to explain the situation. The 9 year old is still in middle childhood and based on the experiment falls under the Concrete Operational stage. Whereas the 13- year- old is in the adolescent stage and falls under the Formal Operational stage. The 9- year old child has the ability to think logically and has the ability to put things in order from least to greatest, but, lacks abstract thinking skills. Abstract thinking is applying information to a problem. Since the 13 year old is more developed, she could think more in an abstract way than the 9 year
