Build a Band
Evidence
My group started out working on our projects separately as a divide and conquer strategy. We chose our materials wisely based on the vibration and wavelength we needed to create. I used metal pipe and a pipe cutter to cut the pipes into the correct length. This precision cut to get the right tune took a long time but worked well to create a full octave of notes. My teammate Victoria created a big ukulele with wood, nails, 20 lbs. fishing wire, and screws. She used nails to create the frets, and used the screws to bind the wood together. My last teammate Aaron created a PVC pipe recorder. He found the appropriate place to drill holes to be able to blow into the pipe and create different notes with a combination of fingers over the holes. This process of build days took about ten hours and some open building at lunches and had some extra classes to finish tuning. We also had time to finish the finesse work of our projects. Our finished products are posted above.
Our Learning Targets
I can use the equation v=f𝝺 to relate the frequency, wavelength, and speed of waves.
I can explain the different ways waves carry information.
I can compare and contrast the wave model and the particle model and understand that both are representations to help me better understand how light behaves.
I can examine and draw conclusions from academic texts to determine the effects of radiation on living cells.
I can explain how waves of different wavelengths are used by a variety of everyday technologies such as cell phones, microwaves, radio, and solar panels.
Vocabulary
Frequency is the number of occurrences of a repeating event per unit of time.
Wavelength is the distance over which the wave's shape repeats. (Crest to crest. trough to trough)
Wave Speed is the speed at which a wave travels. It relates to the wavelength and frequency.
Amplitude is the amount the wave goes up or down from the mid point of the wave to the crest.
Transverse wave is a wave vibrating at right angles to the direction of its propagation. (Ex. vibrations)
Longitudinal wave is a wave vibrating in the direction of propagation. (Sound)
Electromagnetic Spectrum the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies. All travel at the speed of light and this spectrum is from Radio Waves to Gamma Rays.
Reflection
Along this project our group had many difficulties such as losing some of our materials. During the project we could have worked to improved our different team skills. One problem we could have worked on as a group was our communication. An example of our terrible communication, was how we did not share ideas or concerns with each other. We all just started to work separately on our instruments without consulting with each other but, at the end my other two teammates came together to make the guitar. A second aspect we could work on was our time management. Throughout the project we were a little behind on how much we had completed compared to the other groups. If our group had communicated better and managed our time more efficiently we would have felt better about our instruments in the end.
Although we had a few difficulties, we also did some things very well. One thing that we did very well with for example was our character. Our group always respected each other and had lots of fun while getting our work done right on time with no rushing needed. Another thing my group did well was our collaboration skills. The non-rushed work we had to do helped us work better together and helped us produce a great end product on time. In total our group respected each other well throughout the project, but had fun while doing it.
