Charlie: I think the Hammer will stay airborne for the longest because of its wings expanding the further along the back of the plane.

William: I think the Condor is going to win because it looks like it will have good lift ( air flowing upward), and also because the fins at the back look like they will help with the lift.

We know a bit on how to craft some paper airplanes from a sheet of A4 paper. The paper airplanes we are going to be using are some of the average, everyday paper airplanes that you usually think of when somebody says; “paper plane”. As some extra flavour, we will be doing two airplanes that are more advanced than regular paper airplanes.

Our controlled variables are the hight of the scissor lift (14ft), the force we are throwing the airplanes and the type of paper we are using. 

The manipulated variables that we have are the shape and size of the airplanes, and the weight of the airplanes

The responding variable of our project is the amount of time the corresponding paper plane lasts in the air

1. We arrive at the scissor lift with the paper plane contestants.
2. We ride the scissor lift to throw the paper planes and measure the height of the scissor lift to make sure its exactly 14ft high.
3. While we throw the planes, we record the airtime with a stopwatch, and write down the results on a clipboard for each plane’s results. We repeat this 4 times for better accuracy.
4. Once we’ve recorded our results 4 times we take the average of each planes flights with the following formula ((1st flight time)+(2nd flight time)+(3rd flight time)+(4th flight time)÷4) which will equal our accurate results.

Our observations for the different planes are:

Classic: Was able to stay in the air for a reasonable amount of time but usually plummeted to the ground.

Hammer: This is a good plane for going far but not for staying in the air.

Condor: Was able to stay in the air for a long time and went by far the farthest.

Delta: The results were similar to the classic but traveled farther and had less drag (the force that pushes the plane backwards.)

The Raptor: This plane could stay in the air for a long time but, spiraled and often flew back to us.

Barracuda: Being a small plane, it flew fast and stayed in the air for a decent amount of time.

Antelope: This was the smallest plane out of all the contestant planes but, with enough thrust you can make this plane go fast and far. This plane could stay in the air for a long time if you wanted it to. We had to throw this plane with the same amount of thrust as the other contestant planes.

In the end the scores are:

#1 Raptor with 3.94 seconds

#2 Antelope with 2.95 seconds

#3 Condor with 2.29 seconds

#4 Delta with 2.18 seconds

#5 Barracuda with 2.17 seconds

#6 Classic with 1.33 seconds

#7 Hammer with 1.24 seconds

In the future, our experiment can be reproduced, and used for the future manufacturing of real aircrafts. We can also recommend easy to make and efficient airplanes to people who want a good paper airplane.

Some of the things that could’ve impacted our results are, making sure that our throws were accurate and equal so that the results are more accurate.

Another thing that we could do differently next time is that we could make sure that we make four different airplanes for each test. If we did that, it would take a big chunk of time to make all the airplanes again.  A lot of them are very complicated to make, and if we didn't perfectly recreate the planes, there would be mixed results.
