this might not be hi tech enough for high school but i help my daughter build a windtunnel and drilled a small hole in the middle of it, placed a digital balance under it. found several different airfoil profiles, built mini airfoils out of balsa wood and tedlar coated the foil and tested each one at varying wind speeds to determine which foil provides the best lift what what speed. it was easy to build, home depot sells polycarb sheet.
