Narrative:

During flight training, I led my student from the southwest practice area (southwest of W66 airport) toward the csn VOR while the student was under the hood in simulated IMC. We crossed the VOR and headed nebound and inadvertently penetrated the ADIZ (washington class B airspace) without contacting ATC. There was another aircraft maneuvering around the csn VOR and I was distraction with it, instructing my student and observing our distance from the nearby airspace.
