Action Day 2 is considered as smooth and placid as planned: everyone stuck to his or her own schedule and we didn’t experience much pressure. My plan for today is to learn video analysis method and I learned that from Jenny. Using Loggerpro to analyze data was a lengthy work and we had to repeat the same procedure over and over again with different videos. However, the only problem is boringness and everything else went on great. There was also one thing to improve in our experiment: yesterday when we record the video, the hand-written scale was blurry, which added to the inaccuracy of our data. Thanks to yesterday’s trials, our analysis part was good. Our whole team was in a pleasant and placid mood throughout the day. We understand that the most difficult part, data collection, was over, which kind of motivated us. Data analysis was difficult, though, since we had to ensure the accuracy of our work and those data and graphs were dizzy. As a team, we encouraged each other by performing each one’s part well and holding a serious attitude.
Look back to the past two days, there were literally no conflicts in our group. It was surprising that our cooperation was really efficient and natural: everyone can find the part they were good at and contributed to the group in their particular ways. We spontaneous divided into two sub-groups, focused on different tasks in the morning and exchanged our ideas in the afternoon. For example, Jenny and Lilian were Physics HL and Biology HL students, also FM students, so they were good at numbers. Thus, they were mainly in charge of measuring surface tension and data analysis. Bryan and I were more artistic students (he had CS background knowledge and I had Physics knowledge), so we mainly focused on the ship design and material selection on the first day and also did 4 or 5 trials of the real experiment. On the second day, we create video and posters and I did a fraction of data analysis. The clear division of labor makes the cooperation efficient.
There were only one thing left in the preparation stage of our group 4 project: the video recording. We planned to record separately during weekend and add them into our final video.
