Hypothesis (What I think will happen)
I think that the big plane will fly further because  the wing span is bigger so it will catch the wind easier.

 

FACTS

Did you know The first paper plane was made around 200 years ago.

The longest distance ever flown by a paper plane was 88.1 metres.

There are four forces that act on the paper plane when it is flying.

Thrust, how fast it is pushed
Lift, how much wing area can be pushed up
Gravity, pulls the plane down
Drag, slows the plane down
This video shows some information about how paper planes fly. I thought that it does a great job explaining how to make a great paper plane.

 

Equipment that we used

A4 paper
A5 paper
Chalk
Metre stick

Steps (Method)

So me and my partner through the plane 3 times each to get are resaults but then we did it again with the smaller plane and then sadly we forgot to keep track of the scores.

Here are a series of pictures showing how we folded the plane.

First you fold the paper plane in half

 

then fold the top part into two triangles

 

then you bend the sides into upside down triangles at a certain angle so you will achieve flight.

 

then unfold the wings then its ready.

 

We then drew a line with chalk to mark the starting line. Then we took turns throwing the two planes and marking (or taking pictures) or which flew further.

We repeated the throw 3 times.

Results (What we found out)
The big plane flew further.

We measure how far each plane traveled using a metre ruler.
Average distance 3.3 2.3
Conclusion it was an unfair advantage cause it was in the favor
This is where you look at your data and think WHY did that happen?

The big plane flew further than the other plane.

Why I think that the big plane flew further because it has more width plus more density

I did some research and found out that planes with bigger wings fly further because they can generate more lift. Here is some pictures of how it works.

This website also has a great explanation about wing sizes and lift. It also talks about birds which is our teachers favourite thing so I’ll get extra points for adding this!

What I would change
Here, write or make a video on how you would change your experiment if you had to do it again. Talk about the first time you did it when you didn’t make it a “Fair” test.
