This school in a garden is like a real-life Narnia

Starting this September, kids in West Palm Beach, Florida will get to attend a school that's about as close to nature as you can get, short of nailing a chalkboard to a tree.

The Greene School, designed by the Italian firm Carlo Ratti Associati, places kids in pre-K to 4th grade in a so-called "learning garden" - a setting in which lessons take place steps from the outdoors, and every child learns to appreciate both technology and nature.

The school has its own piazza, a "fab lab," and even a secret library in the woods. Take a look inside.
