Final answer:
In Piaget's theory of cognitive development, the concept of Conservation of mass tends to develop first in the concrete operational stage, which occurs from about 7 to 11 years old. Option s a is correct.
Step-by-step explanation:
Piaget's theory of cognitive development highlights that conservation abilities emerge sequentially, with the conservation of mass typically developing before others. In the conservation tasks, children learn that certain properties (like mass, volume, etc.) remain constant despite changes in appearance. Conservation of mass emerges early because children can physically compare and comprehend the preservation of mass.
Objects of different shapes can be visually perceived as having varying sizes, yet understanding that the amount of matter remains constant takes precedence. As children grow older, they gradually grasp conservation of weight, volume, and other dimensions, which involve more complex cognitive operations and understanding of abstract concepts beyond mere physical appearance.
Conservation tasks serve as milestones in a child's cognitive development, with the conservation of mass generally being the initial stage in this sequential progression.
