JOURNALS!
Journal #1 (September 6, 2013)
Today, during Physics class, Mr.Sengez introduced us about STEM and we had to choose a project. He explained the importance of STEM and he told us that it will be a great experience. I participated last year and it was awesome so hopefully this year will be amazing too. I chose gravity tube which is a tubular shape tube that creates different sounds. My demonstration seemed very cool and I was curious about why and how it creates different sounds.
Journal #3 (September 22, 2013)
I researched my project and learned about gravity tube in order to make a powerpoint for Physics. Gravity tube is related to sound waves so I focused on sound waves. I researched on its scientific principles, equation, and the key terms such as wavelength, frequency, and pitch, that I had to know and understand. After I learned more about my demonstration, I am more interested in my project. Gravity tube seems like it only has limited information but there are actually a lot to learn about. Tomorrow, I have to present my powerpoint in front of the class and hopefully I do well.
Journal #5 (October 11, 2013)
Today, I spent my class time in Physics working on my website. I had to put information about myself and my school, Harmony School of Advancement. I briefly introduced myself and my school. I also posted pictures and videos. The page layout confused me at first but Mr.Sengez helped me a lot. This assignment was quite simple. This part of the assignment was very helpful because there will be many times making a web page.It is very important to know how to introduce myself to others.
Journal #7 (October 30, 2013)
Tomorrow is Halloween! Fortunately, I finished posting videos and took pictures of gravity tubes before halloween. I had difficulty while posting the video from youtube because the instructions weren't clearly stated. Mr.Sengez suggested to post it from google drive and it worked perfectly! Pictures and videos are great because it will be easier to understand whenever we are looking at it. Today I learned how to post videos and pictures from my own web page.
Journal #9 (November 9, 2013)
I continued my research on gravity tube. I researched the history connections to the gravity tube again. This time, I searched up when the flute was invented and 2 flutists. It was found about 43,000 to 35,000 years ago in Germany. There are 2 famous flutists who are Johann Tromlitz and Johann Quantz. I related flute to gravity tube because they are both related to sound waves. Not only flutes, I also related other wind instruments such as Danso.
Journal #2 (September 11, 2013)
Website time! Mr.Sengez assigned a homework which is to create my own pbl webpage for my demonstration. Creating a website reminds me of last year because it was my first time doing STEM, so I had no idea what to do. Since this is my second time participating in STEM, it is less of a challenge for me. I just finished making a webpage for gravity tube. I shared my webpage to my social studies teacher and my English teacher.
Journal #4 (September 23, 2013)
I presented my powerpoint today! Unfortunately, I didn't know what to put for the historical connections part so I have to find another time to learn that. I explained that gravity tube has 2 ends. One side has a closed end and the other side has an open end. Open end creates a higher pitch because its wavelength decreases and it has a higher frequency. Closed end creates a lower pitch because its wavelength increases which has a lower frequency. My presentation wasn't that bad, but next time I surely have to be more prepared.
Journal #6 (October 18, 2013)
How does gravity tube relate to history? I answered this question today! My Social Studies teacher, Ms.Morocco and my Physics teacher, Mr.Sengez, gave me ideas about instruments. Only the wind instruments such as clarinet, flute, and etc. are related to gravity tube. For example, if the lower end of the flute is covered with fingers, it will have a lower pitch. I am learning more by connecting my project to history. I haven't thought about relating instruments to physics. I feel more comfortable understanding gravity tube now.
Journal #8 (November 1, 2013)
If you hold the gravity tube vertically and turn it to the opposite side, it makes sounds. When you hold more gravity tubes and flip them at the same time, it makes a louder sound. In addition, if you shake the gravity tube vertically, it will
create different sounds. There are variety of ways to make different sounds. I also learned the equation and learned how to solve the wavelength, frequency, and its velocity. I also learned the SI units for each one. Wavelength is in meters, Frequency is in Hertz, and speed is meter per second.
Journal #10 (November 14, 2013)
Gravity tube is an amazing project. I am glad that I chose this project. If I can choose this project again, I would love to choose this demonstration. I learned that it is good to ask for help if needed. Technology is advancing faster and people will be more familiar with electronics than papers. It would be very useful for my careers when I grow up when I need to make a web page like this. I learned how gravity tube is worked mathematically, scientifically, and historically.
