During the lab experiment, Soaring Straws, the length that the rubber band stretched in centimeters (cm) was the elastic potential energy (EPE). At the point of takeoff, our rocket would contain kinetic energy. It would have no EPE, but its gravitational potential energy (GPE) would continue to grow until it stops at the height of its arc, which is when the GPE would be equal to what the EPE was just before takeoff. Using the information that my partner and I collected, we plotted the results on the attached graph. I found different results of GPE depending on the amount of stretch. Based on the data, we can conclude that the relationship between EPE and GPE is that as EPE increases, GPE tends to increase as well.
We encountered several roadblocks that may have impacted our recorded data. Our launcher kept folding in near the rocket itself. This limited the height of our rocket's flight. Another factor that impacted our lab results was that we put more tape on the extra rubber band resting on the side of the launcher (picture below). This tightened the rubber band that the rocket needed in order to fly, and since the rubber band was tighter, the rocket flew higher. Finally, our accuracy of how high the straw flew influenced some possible outcomes. If we were completely accurate, our graphed results would have become linear. Due to our lack of veracity, the graph is skewed and is not perfectly linear. It is crooked to one side. I feel that this particular lab could be enhanced if the toilet paper rolls that we used as rocket launchers were not as flimsy as they were. Also, we could possibly have a longer straw to use. This could help us when we were launching the straws as it would improve the precision.
