"Introduction to Aerodynamics" by Dr. John D Anderson, also known as
"The Blue Book", is an excellent book for learning fundamental
aerodynamics. It's used here (University of Maryland) for the freshmen
aerodynamics class, which incidentaly is taught by Dr. Anderson (or at
least it was when I was a freshmen). Excellent book, excellent class.
It's not written for the high school crowd but I think it should still
be useful. Many of the examples revolve around low speed wind tunnels,
and if I remember correctly there's even a section on wind tunnel
design. Or maybe that was the white book...don't have them in front of
me.

Good luck!
