Evidence 1: IA Conclusion

The IB describes the knowledgeable attribute as follows: 

• "We develop and use conceptual understanding, exploring knowledge across a range of disciplines. We engage with issues and ideas that have local and global significance."

Having this description in mind, it is clear that my PhyPhox experiment is proof of the development of this attribute. By designing my own experiment, I had to explore my understanding of what I had learned in class. In fact, this was a challenge. Knowing something theoretically is one thing, but really putting that knowledge into practice takes a deeper understanding. Therefore, for me to find out g I had to really dig into my knowledge and enhance my understanding of the formulas I had been learning in class. 

I actually remember that what we were first assigned this project I felt lost. I didn't know where to start. At this time, I decided to revisit my notes—as Robert has always told us to do—and write down a list of ways in which we could calculate g. By doing this, I was able to isolate the simplest and most elegant way of calculating g using PhyPhox. A classical drop test, using PhyPhox's accelerometer to measure the acceleration of my phone while it was falling down.
