Answer:
Piaget believed that children take an active role in the learning process, acting much like little scientists as they perform experiments, make observations, and learn about the world. As kids interact with the world around them, they continually add new knowledge, build upon existing knowledge, and adapt previously held ideas to accommodate new information. Technically saying that the younger the child is, the younger their brain is. Like an adult for example knows what to do and the right things in life versus the wrong things in life. A child wouldn't know the difference because their brains are still taking in things that adults know but just a little bit slowly. Teens brain are still developing but they get the idea of good things and bad things so they (in most cases) choose to do the right things and make the right decisions, but compared to a little kid they're still learning how to write and read and stuff (the basic things) and almost all the time they make the wrong decisions... and that's how you know that their brains has not fully developed.
