Scientific Method in Foam Gliders

For our foam gliders we used the scientific method. Observation: We observed the gliders unmodified and standard. Question: What would happen if I modified my glider to make it better. Hypothesis: If I modified my glider then it will fly better. Experiment: We tested our gliders again to see if they fly better or worse. Conclusion: My glider flew more stable and flew straiter but not as far and fast after I modified it.
