Conservation

Explanation:

According to Piaget's development theory, conservation refers to one accomplishments kids have between ages 7 and 11. When the child has obtained this accomplishment, the child understands that changing the form of a substance or object does not change its amount, volume, or mass. Thus, they understand that objects remain the same when they have changes in their form.

In this example, Mrs. Pearson cut Judy's hot dog into 8 pieces and Sylvia's into six. Sylvia cried because she thought she was getting less hot dog than Judy. Sylvia is not understanding that the hot dog changed its form by being cut into different amounts of pieces but the amount of total hot dog remains the same, thus, she is not understanding the principle of Conservation.
