My PBL project is Harmony Butterfly. This Project consists of a butterfly inside of a jar, and when taped the butterfly moves. However that is achieved by the vibration that moves the butterfly inside, while taping the top of the jar. All because of tension, vibration and the equilibrium inside the jar with the butterfly. A thin wire that is what moves the butterfly inside. I chose this project because I wanted to know more about how the butterfly moves by the tension and vibrations when they tap the top of the jar where the butterfly is place in. So How this project actually worked. Also I wanted to know about frequency and motion. My ELA Project Option is Narrative Essay. I made that choice to do the narrative essay because I want to tell my personal experience while doing the Harmony Butterfly project.
