Information about planes
When we made our airplanes, we had to make the exact same measurements on each material. Reason being, any little fold out of place, any little scratch, or anything else, affects the flight of the plane. Imagine that you have a plane that is badly folded in its left wing. It wouldn’t fly as well as one with perfect folds. Those are simply aerodynamics. Aerodynamics is the branch of mechanics that deals with the motion of air and other gases and with the effects of such motion on bodies in the medium. We made a control which was regular paper. We also made five variables that were silhouette paper, bond paper, newspaper, cartulina, and aluminum foil; each one measured 28x21½. Who came up with the idea of paper planes isn’t clear. Some people have memories reaching way back when, so that shows that even the Wright bros. May have been inspired in paper planes. In the 1930’s, Jack Northrop used paper planes to help in making his ideas for flying wing planes. They also helped to design the Stealth planes (B2 bombers).

Purpose:
We did this project because we always throw paper airplanes without knowing how much it will fly, other times we forget to know the science behind it. We were interested to know which material is better to throw, so we used regular paper, cartulina, bond paper, aluminum foil, silhouette paper, and newspaper to know wich is the material we should use when we want to make a paper airplain and know it will fly a lot; like this we can also know why it flys more time. There is a lot of science behind such a simple thing as a paper airplane and we plan to show you some of it.


Procedure:
1) We researched different types of airplanes and found out which one we were going to use.
2) We decided the measurements we wanted to use.
3) We made the airplanes.
4) We built a hypothesis.
5) We threw each airplane ten times and then we figure out the average.
6) We took notes
7) We made our conclusions
Materials:
- Regular paper
- Cartulina
- Bond paper
- Aluminum foil
- Silhouette paper
- News paper
- Ruler
-Scissors


Conclusion & Resoults
In conclusion, our hypothesys was roung because the bond paper wasent so good althoug paper was really good. We think bond paper dident few well bacause of its wight and its fragility.
Observations & Data
We had various observations in this experiment. For normal paper, we realized that it was the easiest to fold without making ragged folds, because of this the plane flew very well. The aluminum couldn’t be folded without making cuts so it didn’t fly very well. Bond paper was really easy to fold, but because of its low weight, it didnt fly as well as normal paper. Cartulina was a little bit harder to fold than regular paper and it was a little bit heavy, but it still flew really well. Silhouette paper was also easy to fold but it flew kind of bad also be cause of its wight.

Hypothesis:
We think that the material that will fly the bigger ammount of time is paper because is the easier to fold wit out making ragged folds. We think that Bond Paper will be the second best material, because it is the one that is the most similar to normal paper so it was also easy to fold. The difference was that it was a little bit thinner than normal paper so maybe it wouldn’t fly as well as normal paper because it will bend when it flys.
