Hypothesis (What I think will happen)
I think that the big plane will fly further because the higher the weight the higher the chance that it will fly and swing further.
Background
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
- A4 paper
- A5 paper
Steps (Method)
Here are a series of pictures showing how to fold the planes.
Fold paper in half

Fold the ends

Fold the ends a second time

Fold in half

Fold the wings out

Then we took turns throwing the two planes and videoing which flew further.
We repeated the throw 3 times.
Results (What we found out)
The small plane flew further.
(Insert video or pictures here)
Or..
We measure how far each plane travelled using a metre ruler. The results are shown on this table.
Conclusion (what it means)
This is where you look at your data and think WHY did that happen?
The small plane flew further than the other plane.
Why I think that the small plane flew further because it has .….
I did some research and found out that planes with bigger wings fly further because they can generate more lift. Here is a Youtube video explaining why. Especially at 5.30 where he talks about bigger wings generating lift.
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
I’m gonna fold them better and swings the both of the planes in same force.
