# Paper Airplane Lab Experiment - PowerPoint PPT Presentation

## Expertise. Insights. Illumination.

❶Sometimes many experiments need to be done to find the answer. Design an experiment and learn about constants and variables.

That push is a type of force called thrust. While the plane is flying forward, air moving over and under the wings is providing an upward lift force on the plane. At the same time, air pushing back against the plane is slowing it down, creating a drag force. The weight of the paper plane also affects its flight, as gravity pulls it down toward Earth. All of these forces thrust, lift, drag and gravity affect how well a given paper plane's voyage goes.

In this activity you will increase how much drag a paper plane experiences and see if this changes how far the plane flies. If you're flying your paper plane outside, such as in a field, try to do it when there isn't any wind. Fold carefully and make your folds as sharp as possible, such as by running a thumbnail or a ruler along each fold to crease it. Do not bend up the tailing edge of the wings step 6 of the online folding instructions.

This will be the starting line from which you'll fly the paper plane. Did it fly very far? Each time before you throw the plane, make sure it is still in good condition that the folds and points are still sharp. When you toss it, place your toe on the line and try to launch the plane with a similar amount of force, including gripping it at the same spot.

Did it go about the same distance each time? To do this, cut slits that are about one inch long right where either wing meets the middle ridge. Fold up the cut section on both wings so that each now has a one-inch-wide section at the end of the wing that is folded up, at about a degree angle from the rest of the wing.

How far does the paper plane fly now compared with before? Why do you think this is, and what does it have to do with drag? Make paper planes that are different sizes and compare how well they fly. Do bigger planes fly farther? Try making paper planes out of different types of paper, such as printer paper, construction paper and newspaper.

Use the same design for each. Does one type of paper seem to work best for making paper planes? Does one type work the worst? Some people like to add paper clips to their paper planes to make them fly better. Try adding a paper clip or multiple paper clips to different parts of your paper plane such as the front, back, middle or wings and then flying it. The paper airplane experiment, as well as being great fun, is a chance for us to study something called 'The Laws of Aerodynamics'.

When you throw a flimsy paper dart across a room, you might not realize that it follows the same laws of flight as a Jumbo Jet! With just a few pieces of paper and a little patience, you can explore these laws and find out how a big piece of metal manages to stay in the air.

For this experiment, we are going to chose five different designs of plane. One place to look is www. You can use any design you like, as long as they are different and you don't use any scissors or tape to make them.

In the paper airplane experiment, we are going to test which designs fly the furthest. Some of the designs have a sharp point so do not throw them at anybody's face! You should work out an average distance flown for each type of plane in your paper airplane experiment. However, we are going to use something called an adjusted average. Do not use the lowest and highest figures to work out your average, just the three in the middle.

This is because; in an experiment like this, a gust of wind or a bad throw can make one or more of your results wrong. This is called an outlier-data. After you have worked out the average for each, you can plot a bar chart and discuss the results with your class.

Which planes flew the furthest? Why do you think they were the best fliers? There are many more experiments you can perform with paper airplanes.

Maybe this is the first step on you journey to being an airplane engineer or designer! Figure 1 - The distance flown by paper airplanes. Check out our quiz-page with tests about:. Martyn Shuttleworth Sep 21, Retrieved Sep 14, from Explorable.

If the paper plane has enough thrust and the wings are properly designed, the plane will have a nice long flight. But there is more than lack of thrust and poor wing design that gets a paper plane to come back to Earth. As a paper plane moves through the air, the air pushes against the plane, slowing it down. This force is called drag. To think about .
