Science Air & Flight Assignment Our goal: To design a paper plane
incorporating and demonstrating
the principles and forces of flight,
thus creating a loop or turn while
in the air. Materials used Conclusion Manahil, Kamini, Fariha and Abdullah The Educational
Part of It Our group soon learned that this project isn't just about designing a plane for amusement. This assignment helped the group explore deeply into how the Bernoulli's principle and the four forces of flight help any type of aviation technology. With the damage of all sorts of parts in our plane and with our plane crashing into unsafe and uncharted areas, we soon figured out it's tough to be an airplane engineer. We also worked really hard altogether, so we hope you enjoy. ; Our design works using the Bernoulli's principle. The Bernoulli's principle has to do with the shape of the wing. Our design included the theory of the Bernoulli's principle and I know this because, the Bernoulli's principle demonstrates that the wing(s) on a plane has a curved top and a flat bottom. Even though with typical paper planes, the curve was difficult to see, it was still curved. Our plane successfully flew which means it was curved at the top somehow and its bottom was flat. This amazing presentation is brought
to you by: The KMAF Group. (Kamini,
Manahil, Abdullah and Fariha.) Materials used
• Paper
• Staples
• Tape Instructions to building our plane • Fold a piece of paper vertically

• Open the paper so it has a vertical line down the middle, fold the top two corners so they meet to the vertical crease in the middle

• Fold the corners down to the crease so the corners are under this fold

• Fold the two top corners created in the previous step to the center crease so that the points are about 2/3 of the way down the center crease flap.

• Fold up the point that has been covered in the previous step so that it secures the flaps against the crease

• Fold the paper in half so that all the folds made in the previous steps are facing outwards. The small triangular fold is now along what will later be the bottom of the plane.

• Fold both side flaps down to the bottom so that the wings are perfectly aligned with the bottom of the airplane.

• Unfold the wings slightly so that they are next to the body of the airplane Testing the original design for our plane Trial # Observation- Distance travelled, Loops made
1. 2 loops, 1 turn, 4 metres
2 . 3 loops, 2 turns, 4.3 metres
3. 3 loops, 1 turn, 6 metres Hypothesis If I change the nose of my plane and add tape or a staple to the nose. It will increase the durability. Also the nose of the plane will not be crushed or deformed when it hits the ground. It will now stay the shape form it was meant to be. Testing the design for my second plane Trial#Observations-Distance Traveled, Loops Made
1. 3 loops, 2 turns, approximately
5 meters
2. 3 loops, 2 turns, exactly 11.9 meters
3. 4 loops, 1 turn, approximately
7 meters Conclusion Continued Our design included each of the following topics which were taught in class

Our design included all the four important parts of flight (Drag, Lift, weight, thrust). I have described below the ways that the four parts of flight tied into our designs.

Lift

Lift is the force that keeps the plane in the air. Our plane did fly for about 20 seconds at the most, which means that it demonstrated lift.

Weight/Gravity

With planes, weight/gravity works against lift to pull the plane towards the ground. Our plane did crash after making turns or a loop, which means it did demonstrate weight.

Thrust

Thrust is the force that results in the plane moving forward through the air. Thrust was produced when we threw the plane. It did move forward and it didn't crash immediately into the ground.

Drag

Drag is the force in the plane that brought about the slowing down of the plane. This can be explained using an example. In the same way, the plane was trying to move through the air and it also tried to push approaching air out of the way to fly a longer distance. When I flew the plane the wind/breeze caused by people running around or by the door being opened slowed down the plane. Thank You
