Hi Rusty!
Well, for a practical demonstartion, I would recomend NASA's "FoilSim". This program is available through their homepage under "Education" and allows you to design a given airfoil and conduct measurements of physical properties of the air flowing around the airfoil.
If you are looking at making a presentation, I would recommend starting with the properties thickness and camber and then relating them to viscosity & Reynolds-no.
Good luck with your project!
Best rgds,
Ivan
