9 Year Old Conservation

The idea of conservation is when someone changes the shape of the substance in which it does not change the amount volume or mass. This is to see if children can think logically. In the experiment there is going to be two girls that are going to be tested over one 9 year and 13 year old. My prediction is that the 9 year old will not be able to conserve.
The first experiment was using the 9 year girl. The experimenter first pour the same amount for each cup then ask the participant if there is the same amount of juice. The 9 year old says that “They are both the same”. For the second experiment was using the short and long container. The short container was pour into the longer container. Then the experimenter ask the 9 year old girl if there is the same amount of juice? The 9 year old girl that “they both have the same amount of juice”.
I did the same experiment with the 13 year old and the child responds the same thing.
The 9 year old is in the Concrete Operational stage and the 13 year old is in the formal operational stage for Piaget’s theory. The 9 year old is still in middle childhood and the 13 year old is in the adolescent stage. The 9 year old child can think logically and they can order things from least to greatest but, they can not think abstract yet. The 13 year old can think abstract and think more about complicated stuff.
The experiment is between two children one 9 year old and one 13 year old doing the conservation task. Conservation is when you change the shape but, you do not change the amount of the
