1. Introduction

Our groupʼs topic is the angle of paper airplanes. We want to fly airplanes for

a long distance. We think important thing is the angle and so our groupʼs topic

is the angle.

Goals

Our group had two goals.

First, we wanted to know what kind of paper airplane was the most regular.

Second, we wanted to know what makes a paper airplane regular.

2. Method

Airplanes

We selected three airplanes.

Airplane1 It was little difficult to make. Its wings were large size.

Airplane2 It was easy to make. Its body was little size.

Airplane3 It was the most difficult to make. Its body was very sharp.

Steps

Do step 1 : To make three airplanes.

Do step 2 : To fly airplaines.

Do step 3 : To time flying airplane.

Do step 4 : To measure the distance the airplane flew.

Do step 5 : To put the data into the computer.

Research angles were 30°, 45°, 60°.

3. Results

We collected 89 data points. Below you can see a table showing our data.

Table

Airplane Number of throws Average distance between airplane

Airplane 1 14×3 4.0m(30°) 6.4m(45°) 4.1m(60°) Airplane 2 1×3 0m(30°) 0m(45°) 0m(60°) Airplane 3 15×3 8.9m(30°) 7.6m(45°) 4.4m(60°)

Chart

↓Airplane 1 (blue 30°, orange 45°, gray 60°)

Airplane2 No data

↓Airplane 3 (blue 30°, orange 45°, gray 60°)

Airplane2 canʼt fly. Because it did not fit in the machine.

Airplane3 (30°) had the longest average distance (8.9m). Airplaine1 (30°)

had the shortest average distance (4.0m).

Airplane3 flew farther than Airplaine1. Sharp body airplanes can fly well.

Average angle

angle distance

30° 6.5m 45° 7.0m 60° 4.3m

Best angle is 45. Airplanes flew the farthest at this angle.

4. Conclusions

The data shows that Airplaine3 was the most regular. We think this is because

it had sharp body and small wings. Sharp body and small wings did not get air

resistance. The data shows that Airplane1 did not fly a long distance because

Airplaine1 had large wings. The best angle was 45°.

We think flying well airplane is sharp body , small wings and 45°angle.

Next, we want to test all airplanes at the angle of 45°.

We want to know the best shape for airplane.
