Default please help with science fair question

can someone please help me? i need a science fair question that is specific, quantifiable, it states what i am going to observe, and it states the variable (1 variable.) i'm thinking of "which wing design creates the greatest lift?" if you have one that has all the requirements that would be great also. please answer back. you can email me at [email]xalxhrndez11x@netscape.net[/email] if you wish. thnx

Default Wing Design and Lift

Start by going through this webpage [url]http://virtualskies.arc.nasa.gov/aeronautics/tutorial/wings2.html[/url]

Then, if you have any specific thoughts, let us know!

well the wing shape is thin at the end I think ... and the middile or somthing moves for lift up than changes to suit it flying or you can researdh on bird's wings because that is how inventors got the idea...

That could've caused an injury'.
But clever Isaac alone could see,
The situation's true gravity.

Hi.

When you work on your project, have in mind that velocity and pressure are key for the lift in wing design.
The greater the velocity in the upper face of the wing (thus a result of lower pressure in the upper face), the greater pressure in the lower face of the wing and thus a greater lift.

Good luck with your project.

Oscar
