We often think of a classroom as essentially... A room.  But there are days when mother nature offers far more enriching learning opportunities in the open.

And the effort and expense to build one of these in your school is minimal.  It is really surprising to think that every school doesn't have one when you consider the opportunities it offers students and teachers to break the mold every now and then.

I came a across these simple plans from kaboom that outlines one idea but I am sure that you could adapt this to suit your needs.  You can download them here.

I'd love to hear from anyone who has had any experience in this field and could share their insights.
