This Unit
In this unit we studied longitudinal and transverse waves and how they reflect or refract when they come in contact with a materiel. We also studied wave speed, wave length, frequency, period, and amplitude. At the end of the unit we had a project where we were tasked with building three instruments; a wind, a chime, and a string instrument. These instruments all had to be able to play the notes A4, B4, C4, D4, E4, F4, and G4. Then we had to use what we learned to explain how each of them work.
Concepts
- Transverse Waves - waves where particle movement is perpendicular to wave motion
- Longitudinal Waves - waves where particle movement is parallel to wave motion
- Wave Speed - velocity of a wave
- Wave Length - distance from one crest to crest of one wave
- Frequency - number of waves per second
- Period - time for one wave
- Amplitude - the height or magnitude of the wave

Reflection
In hindsight, I think my group and I did very well on this project. We worked together well, we and we were able to explain how our instruments worked. Personally, I though this was one of the most frustrating projects of the entire year. Since two of the instruments we made were very fragile and something would all ways brake on them. However, as I said everything went well.
During this project there were two things that I did well. First, I was productive during this project. When ever I had to the chance to work on my portion of the project I would use it and when I was done I ether moved on to the next part or helped my teammates. Second, I was somewhat of a leader. In the beginning of the project I help slit up the work among us and later in the project I did my best to make sure my team mates were doing something productive.
On the other hand, there were two things that I need to improve on. First, was my attitude. As I said already, I got very frustrated with this project. Because of that my speech and behavior were not appropriate. Second, was my cooperation. Even though we did work well together. I sometimes didn't with them cooperate. During the project, I decided to use aluminum bars instead of the metal pipes which for the xylophone. Even though we had easier access to the pipes which in turn would have save me lot of time. I was stubborn and wanted to do what I wanted to do. So guess it sometimes better to listen to your group.
