Forces

Aim: To understand forces, to create the most stable, straight line paper plane flight.

Hypothesis: Although I'm not going to make a paper plane, I still predict that it would go about half away.

Forces on a paper plane

Forces can make your paper plane balanced, if your plane is balanced then it can fly straight. 

Gravity: Gravity is the force that pulls the plane down

Drag: Drag is the force that pulls back the plane

Thrust: Thrust is the force that pulls the plane forward

Lift: Lift is the force that lifts the plane, making it stay in the air

Method:

1. Fold A4 piece of paper in half (long ways).
2. Then open it back
3. Fold the top corners into the centre.
4. Then fold the corners again to the centre.
5. Then fold it in half (long ways).
6. Then fold the wings outwards.

Results:

Our plane flew up to half of the room and then went another direction. We didn't really get the measurement of how long our plane went. 

In our practice the plane flew all the way across the room but when it was the real thing something changed in our plane.

Discussion:

I learned that, different paper planes can fly different distance. Some are great that they can fly across the room and some good that they can fly up to half of the room.

I wouldn't really change anything because the plane we made was really great. It could fly across the room but there was just a slight change when they threw it.
