dhara,
I skimmed through the experiment and I think I understand your question. When it talks about "aerobic" and "anaerobic" conditions, it means how much air is in the water (not above the surface). So when you boil the water, that takes all the bubbles out. Then, for the +air condition, you add air back in with the aquarium pump. The -air condition remains as it is.
This is similar to what scientists do in labs; they grow cultures on a shaking platform so that air bubbles are always swirling around the solution. And after you do the experiment, you'll understand why they do it that way.
Good luck.
