1. SAMPLE: Fair Test Experiment Paper Airplanes John Doe and Jane Smith Mr. Tripp North Middle School

2. BRAINSTORM We are doing an experiment with Paper Airplanes

3. Variables and Constants Independent Variable: Weight of Paper Airplane Dependent Variable: Distance (cm) of flight Constant Variables: Design of plane, type of paper used, how you throw the plane, where you throw the plane.

4. Testable Question How does the weight of a paper airplane affect the distance it flies?

5. Hypothesis If I throw paper airplanes with different weights, then the heavier plane will fly the farthest.

6. Procedure • Make a paper airplane by using a design of your choice. • Go to an open location like a gym or hallway and throw the plane. • Measure the distance of flight with a tape measure in centimeters. • Throw and measure the plane again for 2 more trials. • Repeat steps 2-4 by adding 2 paperclips, then 4 paperclips.

8. Graph Distance of flight (cm) Weight of paper airplane

9. Conclusion This experiment was to determine if the weight of a paper airplane affects the distance it flies. My hypothesis was the heavier plane would fly the farthest. The data does not support my hypothesis because the plane with 2 paperclips flew the farthest with an average of 245 centimeters, and the heaviest plane with 4 paperclips only flew an average of 100 centimeters. To further this experiment we would like to determine if the design of the airplane would affect the distance it flies.
