Children are curious and creative. (Science and Art)

One commonly hears that children enter the school system naturally creative.  But by the time they graduate, we somehow manage to squeeze it out of them.

I am currently substitute-teaching in middle-school science, and am seeing a corollary.

Children enter the school system naturally curious about the world.  i.e  They make good scientists.  But by the time they graduate we somehow manage to squeeze it out of them.

Of course, they don't have many of the skills needed to 'carry out' science.  But, similarly, they don't have many of the techniques and vocabulary in the arts.  That's why we teach art in school.
