The document describes an experiment to test how different paper airplane designs affect flight speed. Three designs - Harrier, Martin, and Galaxy Fighter - were tested by measuring the time and distance of each plane's flight over three trials. The Martin design traveled the farthest distance and fastest speed on average, while the Galaxy Fighter design was the slowest. The experiment had one independent variable (paper airplane design), one dependent variable (flight speed), and controlled for paper type, weather conditions, and launch force.

1. I. Problem: How does changing the design of making a paper airplane affect the
speed of it?
II. Hypothesis: If we use different design in making a paper airplane, then it can affect
the speed of it.
Experimental Design
III. Experimental Group: Different design of a paper plane
Control Group: Normal design of paper airplane.
Independent Variable: Different design of a paper airplane.
Dependent Variable: Speed it traveled
Control Variable: Type of paper, weather, force applied to the plane.
IV. Materials:
 3pcs. of bond paper (short)
 Stopwatch
 Scissors
 Ruler
 Pencil
 Pull, push and roll
V. Procedure:
First ready all the materials needed in this experiment. After that, start folding the
first bond paper to the “Harrier de Sign”. Fold the second to the “Martin design”. And
fold the last bond paper to the “Galaxy Fighter Design”. After folding/making 3 design,
start the experiment.
Throw the first design of paper airplane which is the “Harrier Design” with normal
force applied to it. Measure it’s distance and time using a Stopwatch and a Pull, Push
and Roll then calculate the speed of the airplane using the time and distance that

2. you’ve gathered. Repeat the process on the “Martin and Galaxy Fighter Design”.
Record all the data that you’ve gathered on the table below.
