How does the wing span effect the distance the plane goes?

Hypothesis: If we make the wing span  bigger, then the plane will go further because it will generate more lift.

Dependant Variable: Distance

Independent Variable: Length of Wings

Controlled Variables: Size of paper, printer paper, thrower

Materials: Paper, ruler, pencil, tape measure, note taking page

Plane 1: The Standard Plane (11cm Wingspan)

Plane 2: The Arrow (8cm Wingspan)

Plane 3: The Bat (20cm Wingspan)

The hypothesis, if we make the wing span  bigger, then the plane will go further because it will generate more lift is rejected  The data shows that “The Standard” went an average distance of 5 meters 98 centimetres, “The Arrow” went 6 meters 51 centimetres, and “The Bat” went 6 meters 8 centimetres. “The Arrow”, the plane with the shortest wing span went the furthest. It went 53 centimetres further than “The Standard” and 43 centimetres. “The Bat” went further than “The Standard” by 10 centimetres which is what we had predicted but what we didnt predict was how “The Arrow” went the furthest.

The results of this investigation are useful because it shows how important aerodynamics is.

The investigation can be improved by using a machine to get the exact same throw every time, getting better measurement by finding longer meter sticks to line up with the plane, finding a spot where there are no obsticals or wall and folding the planes perfectly.

Other questions that need to be answered are: Will using different types of paper (like construction of craft paper) effect he distance?
