The purpose of this project is to make a real working guitar out of a tissue box

Each student has to work individually in his/her own guitar

Dee what the function of a guitar is How can sound be produced by a rubber

band?

Standards 4a) Sound Is a longitudinal wave whose

speed depends on the properties of the medium in which it propagates

Objectives1.Design and construct musical instruments

exclusively make of shoe box/ tissue box2.Explain the physics of music3.Explain why there are variations in sound

among instruments and among voices

Problem How can I make a guitar that sounds and

ias tuned like a normal guitar?Hypothesis If I cut the rubber band and tie them around

the sticks at the top of my box, then I can continue to tie them until they are in tune

1. Tissue box2. Rubber bands3. Popsicle sticks4. Paper fasteners5. Construction paper6. Paper

1. First, I cut open a hole at the top of my box and covered the box and paper roll with construction paper

2. Then, I put holes into my paper roll and stuck popsicle sticks in the roll

3. Insert the paper roll into the tissue box and hot glue in place. Then place paper fasteners at the bottom.

4. Cut rubber bands and tie one end to the paper fastener and the other at the popsicle stick at the top.

5. Hot glue popsicle sticks at the bottom of the rubber bands in order to elevate the strings.

While working on my guitar I noticed that the thicker the string, the deeper the sound. Vice versa, the thinner the string, the higher it sounds.

The physics of music is that when you pluck the strings of the guitar or use a bow on the violin or hit a key on the piano, the movement causes vibrations. These vibrations in turn produce sound.

This vibration is carried in the air as a longitudinal wave and we are able to pick up the sound and decipher the pitch.

In conclusion, my hypothesis was correct, because I was able to tune the guitar by wrapping the rubber bands around the popsicle stick until I got the right sound.

Now you are able to hear the scale on my guitar.

This project was a simple one. Making a guitar was fun. The only difficult part was when I tried

tuning my guitar because after awhile, they started to sound weak in a different pitch.

So I had to constantly fix them.

No hitting anyone with your guitar or any other materials

No pointing materials at classmates Don’t play with anyone’s projects

Music is everywhere and can be played on the simplest things

An issue with music is that many schools cut funds for music classes

This is a serious issue because not only do the students lose another extracurricular activity, but they also lose a chance to find a hidden talent and a chance to play a favorite past time.

They also lose the chance and joy of playing an instrument.
