In the video for Piaget, a young girl thought a was evenly divided when the research assistant split it into 2 pieces. What was the item, and which of Piaget’s stages would a child be in who does not yet have this ability to conserve?

Without the ability to understand the conservation principle, young children often make mistakes about the quantities of different different objects after they have be split into different proportions. The typical experiments or this are the same amounts of liquid in differently shaped glasses or a ball of clay that has been flattened.

Explanation:

The video was not provided to know for sure what object was divided into two pieces in the described experiment. The ability to conserve is associated with the concrete operational stage which develops from ages 7-11. It refers to the ability to think logically about the quantities of items. This signals when children have this ability they know that the quantity does not change just because of the size of the container or the shape that is given an object. Piaget's theory was that children do not have this ability during the preoperational stage of their development from ages 2–7.
