I have just finished working on origami with my students and the fifth and sixth graders have just finished a unit on flight and made rockets. I am going to suggest that they look into making these origami hang gliders. It sounds great. I haven't made any yet, but hope to this summer. This web site, http://www.sciencetoymaker.org/hangGlider/index.htm has directions to build and surf your hang glider. It looks fantastic.
This Science Toy Maker site looks like a real find. All projects use very cheap materials and there seems to be a lot of science explanations about why they work. Maybe this summer, you could spend some time looking at this site.
