PROBLEM

Does a paper airplane designed with more surface area allow the plane to stay aloft a longer amount of time?

BACKGROUND KNOWLEDGE

Several forces combine to affect an airplane’s ability to fly.
Thrust – A push that provides the plane with its initial acceleration
Lift - Air moving under the wings of the plane providing an upwards force
Drag – Air pushing against the plane, causing it to slow down
Weight – The weight of the paper airplane that brings it to a landing
Gravity – The weight of the force of the Earth’s gravitational pull


HYPOTHESIS
I believe that model number 6 with stay in the air the longest. I think this because the design allows the plane to have a large amount of surface area on the wings, which should allow for upwards lift as the plane moves through the air.







INDEPENDENT VARIABLE:
The independent variable in this experiment is the different designs that each airplane was formed into.
DEPENDENT VARIABLE:
The dependent variable in this experiment is the amount of time that the airplane stays aloft. Measured from the time the plane leaves the launchers hand, to the time the airplane lands on the ground.
CONSTANTS:
The height of the airplane’s launch
The material used to construct the airplanes (copy paper)
CONTROL:
Each different airplane model will serve as a control against the other models.


REPEATED TRIALS:
10 Different models airplanes launched 3 times each under the same conditions.

MATERIALS NEEDED:
Standard Size Copy Paper (8 ½ in x 11in)
Stop Watch
Launch zone with no weather variables
Lab Notebook to Record Results

...e plane to test the affects of weight in specific locations.
Using the same plane designs, test each plane for distance traveled.

Critical Thinking Question/Learning Extension:
The Wright Brothers First Flight
Forces That Act Against an Object In Flight
Engineers use their knowledge of forces and motion as well as trial and error to create new machines. What changes would you make to your airplane and why?

SOCIAL SIGNIFICANCE/APPLICATION
This paper airplane experiment allowed me to explore the laws of aerodynamics and the important role that they play in our everyday lives. Airplane travel is among the most widely used forms of travel in the word. In fact, an estimated 8 million people fly in airplanes daily. Without the help of aviation experts to analyze the small scale date of a model airplane, modern travel as we know it would have never been possible.

Aerospace Industry: Boeing Airplane Company’s Attempt to Utilize the Outsourcing Method

- As with any business model, the aerospace industry strives to lower costs and increase profits. With this objective in mind, the practice of outsourcing has become increasingly popular. The concept of outsourcing the manufacture, production and design engineering to low-cost countries in order to reduce cost and increase profits has, in some cases resulted in the opposite effect. This study will explore the Boeing Airplane Company’s attempt to utilize the outsourcing method for its new 787 Dreamliner program....   [tags: history, expectations, network]

Physics of Paper Airplanes

- Paper Airplanes, flight at its simplest for humans. As kids, we learned how to build paper airplanes and send them soaring into the sky. We didn't stop to think about why the airplanes where able to fly after the initial thrust we gave them or how they were able to glide for so long afterwards. Ignorance was bliss then, but now we strive to understand how things work. Looking back to the childhood past time of flying paper airplanes, I will try to explain some of the parts that make paper airplanes fly....   [tags: Physics Science Planes Plane Airplane]

The Effects of Our Ecological Footprints Essay

- ... Likewise, because of high quality life, almost every family in America owns at least one car, which also builds up carbon dioxide emissions to the atmosphere. Thus, America contributes to high carbon footprint and this would lead to global climate change. US&Canada region has the greatest total footprints. It may cause global environmental challenges like global warming, deforestation. I think it has the greatest environmental impact on our planet. After doing the footprint calculators quiz, I found my estimated ecological footprint is ?global hectares, which is lower than the Canadian average but higher than the total world average (Global Footprint Network, 2011)....   [tags: human affect on our planet, lifestyles]
