You parts paper planes of a term just
In your lab notebook, create a data table like this one. For each flight, write down how far the paper plane travels in centimeters [cm] or meters [m]. Go to a large area to fly your paper plane. Make sure that there is no foot or car traffic at the area. A long hallway or your school gym is a good location.
If you are flying your plane outside, like in a baseball field or on a basketball court, do your experiment on a day when there is no wind. Tear off a 5-foot-long piece of masking tape and tape it to the ground in front of you, going from left to right. This will be the starting line from which continue reading will fly the paper planes.
If you are doing this science project outside, you could use a line of sticks or rocks to mark the starting point. Practice throwing or launching the paper planes. You will want to launch the planes in exactly the same way every time. Hold the planes at exactly the same spot on the plane every time you launch a plane. Once you have finished practicing, it is time to start the experiment. Place your toe on the starting line you prepared earlier and then throw one of your planes. Use the tape measure to measure how far in centimeters or meters the paper plane flew from the starting line.
Record this distance in the data table in your lab notebook. This will be "Flight 1" for "Plane 1. If your tape measure does not have metric units, you can convert inches or feet to centimeters or meters using this website: Science Made Simple, Inc. Length conversion using online length converter by Science Made Simple.
Retrieved February 13,from http: Doing these repeats will help ensure that your data is accurate and reproducible.
Before you fly the plane, make sure that it is in good condition and that the folds and points are still sharp. Record the distances in the data table in your lab notebook all in the same row as "Plane 1," as "Flight 2," Flight 3," "Flight 4," or "Flight 5. Look at the back of the plane, where the wings meet the ridge in the middle. Using scissors, cut slits that are 2. Fold up the 2. How do you think this increases the plane's drag? To increase the paper plane's drag, first cut slits 2. Each wing should now have a 2. Using plane 1 with added drag, repeat steps Record the distances the plane flies in your data table in the row titled "Plane 1 with Added Drag.
Repeat steps using one of the other two planes you made in step 2. Record the distances the plane flies in the row titled "Plane 2" and then "Plane 2 with Added Drag" once you repeat step In your lab notebook, record any observations you make. Repeat steps using the last of the three planes you made in step 2. This plane should not have been flown previously. Record the distances the plane flies in the row visit web page "Plane 3" and then "Plane 3 with Added Drag" once you repeat step Analyzing Your Data Using the data you collected in the data table in your lab notebook, calculate the average distance that each plane traveled, with and without added drag.
Record your results in the column labeled "Average" in the data table.
For example, if plane 1 traveled 4. Use the data from your data table to create a bar graph. You can plot your data by hand or you can plot your data online at Create A Graph. Label the x-axis the horizontal axis "Paper Plane" and label the y-axis the vertical axis "Average Flight Distance. Make each bar go up to the average distance that plane traveled.
What does your graph tell you? How did adding drag to your paper planes affect how far they flew? Can you explain your results in terms of how forces allow a plane to fly? Re-read the Introduction in the Background tab. Use a Wind Tunnel Simulator It was pretty easy, fast, and inexpensive for you to test different versions of a basic paper airplane with added drag.
But what about engineers who have to design and test real airplanes that cost millions of dollars? It would be much too expensive to build and test each different version of the plane. Engineers use wind tunnels to test smaller models of planes, which is much faster and cheaper. To allow even quicker testing, they can use computer simulations of different plane designs, then they do not have to build a physical model at all, and can do all the testing on a computer.
In this project, you can use simple, free wind tunnel simulation software called Flow Design to compare different versions of your paper airplane. Flow Design simulates the flow of air around a three-dimensional object illustrated by the colored lines in Figure 3, below and calculates the drag force on that object. Flow Design will help you visualize how the air flow changes around the plane, and how the drag force increases, when you add flaps to the plane, as described in step 11, above.
These screenshots of the Flow Design software show simulation of airflow around two different paper airplane models. The plane on the top does not have flaps on the back, so the airflow is very smooth. The plane on the bottom has flaps that make the airflow much rougher this is known as turbulence. To get started using Flow Design to analyze different paper airplanes, follow these steps: Follow the directions at autodesk.
This requires creating a free Autodesk.
Links to these styles can be accessed by the buttons below. Because darts don't have a lot of drag and lift, they depend on extra thrust to overcome gravity. This modification noticeably affects the flexibility which allows good launches. Does one type work the worst? Opposition to pwper scientific ideas, by scientists and non-scientists.
Remember to check the system requirements at http: Download the 3D design file for the regular paper airplane and save it on your computer. Download the 3D design file for the paper airplane with flaps and save it on your computer. Read the instructions and watch the videos at http: Spend some time getting familiar with the software before you continue. Flow Design is also available as a plugin for other Autodesk programs called Inventor and Revit, which have different interfaces.
One at a time, open the "regular paper airplane" and "paper airplane with flaps" files in Flow Design. View the streamlines, or lines representing what to do with used paper towels flow around the models. How do they differ for the two different models?
Flow Design also calculates the drag force on each model. Is the drag force bigger for one of the designs? If you really want to be creative, and design and test your own paper airplane models, you can use Computer-aided design CAD software to design any type of paper airplane that you can dream up, and then test it in Flow Design. If you want to try designing your own paper airplanes in CAD, refer to the Science Buddies abbreviated project idea Design and 3D-Print Your Own Robot!
I think I will try for zero washout, as this should provide the lowest drag during the ascent. Does the type of paper you use affect how far the paper plane flies? For the world record paper airplane this gives a minimum sink speed of about 2. Swing your hand back and forth. Any time you need to include the exact words, paragraph, sentence, or even short phrase that is unique, specific, original, or particularly apt, its author deserves credit with a specific reference. It landed on the shirtfront of the French Minister of Education, much to the embarrassment of my sister and others at the banquet. The flat wing at high lift results in a steep pressure gradient near the front of the wing on the upper surface, which likely aids transition to a turbulent boundary layer which is needed for low drag at high lift.

I Did This Project! Please log in and let us know how things went. Variations Does size matter? Make planes of different sizes but keep the design and the type of paper you use the same.
In general, the lower the Re, the greater the camber. If you are doing this science project outside, here could use a line of sticks or rocks to mark the starting point. Includes references to low Reynolds number drag throughout] Hoerner, S. Record this distance in the data table in your lab notebook. These often contain additional information not in the book being reviewed. Inorigami artist Michael LaFosse designed a pure origami one sheet; no cutting, glue or staples Secondary sources are useful ppanes leads to primary sources and as a way to gain an overview of your subject and initial familiarity with it. This could improve the span-wise lift distribution which could improve the "e" in the sink rate equation. One of the most important things I learned was that Cdo, zero lift plaanes drag, is more important in the ascent than it is in the descent.
Do bigger planes fly further? Do more complicated planes fly further? In order words, does the number of folds that you use to make a paper plane affect the distance that it flies? Try this out using the same size and type of paper. Does the type of paper you use affect how far the paper plane flies? Try making paper planes out of different types of paper, such as printer paper, construction paper, and newspaper.
Make all of the planes using the same design and fly them as similarly as you can. Does one type of paper seem to work best for making paper planes? Does one type work the worst? You may need to do several trials to see a trend. Some people like to add paperclips to their paper planes to make them fly better. But where should the paper clips be placed for the best flight? Try adding paperclips to the back, the front, the middle, or the wings.

You can add one paper clip or several, but try to be consistent with how many you use. Take notes in your lab notebook so you know what you tested. Does adding paperclips somewhere make the paper plane's flight better, worse, or have no effect at all?
