Question

When Ernesto sees his mommy roll the thick ball of dough into a thin circle for a pie crust, he says, “Now there is more dough, because it's bigger.” His sister Lara tells Ernesto, “No, it's the same amount because Mommy could just roll it back again and it would look the same.” According to Piaget's framework, Ernesto can't conserve and Lara can _____.

Answer 1

Conserve.

Step-by-step explanation:

According to Piaget's framework, Ernesto can't conserve and Lara can conserve. According to Piaget's Theory of Cognitive Development conservation of matter is a process. Ernesto has seen the changes in the dough but he thinks there is more matter. On the other hand, Lara has seen the changes too, but she realized that the amount of dough is the same before and after the changes. No dough was added or taken from the original amount. This is called reversibility and is a necessary condition to acquire conservation.
