Helicopter Lab
Helicopter Lab * Objectives: the objective is to study the effect of variables on the helicopters’ flight. The goal is to observe which can stay in the air for the most time. * List of materials: 3 patterns for a paper helicopter, scissors, tape ruler, and paper clip. * Procedures: 1. Cut the solid lines and fold the dashed ones. Fold A toward you and B from you to form wings. Then fold C and D inward to overlap, forming the body. Fold up the bottom on the dashed line and hold it with a paper clip. Finally drop it from 2 meters and measure the time. 2. Complete procedure 1. Add two paper clips on the helicopter. 3. Complete procedure 1. Fold 2 cm of wings upward.
| Trial 1 | Trial 2 | Trial 3 | Average speed | H1 | 0.935 m/s | 0.985 m/s | 0.98 m/s | 0.965 m/s | H2 | 1.35 m/s | 0.99 m/s | 0.985 m/s | 1.05 m/s | H3 | 0.81 m/s | 0.89 m/s | 0.8 m/s | 0.8 m/s |
H = Helicopter m/s = meter / second
* Conclusions: 1. The helicopter with two paper clips floated in the air for the most time because of the speed, which gave it less time to spin its wings. 2. The helicopter with folded wings floated for less time because there was less area in its wings to fly. 3. Repeated trials and more test subjects are suggested for improvement of
