Properties of Sound Lab- Experiment 1

Properties of Sound Lab

Procedure:

Experiment #1: Amplitude

1.       Have 2 partners each hold one end of the thicker rubber band, pull until the rubber band is not loose.

2.       Pull the rubber band 1 cm away from the middle. Let it go. How far does the band move? (1 cm) Describe the sound you hear in the table below.

3.       Repeat step 2 four more times. Each time, pull the band back further. Describe how the sound changes each time in the chart below.

Distance away from middle	Description of sound
1 cm	Low bing
2 cm	Little higher bing
3 cm	Even more higher bing
4 cm	Even higher than the last bing
5 cm	This is the highest of all the bings

Conclusion-

To conclude this experiment the farther the distance from the middle of the rubber band the higher the pitch. I noticed during this experiment that the ‘bing’ sound increased when I pulled the rubber band away from its starting point.

Further Inquiry

I wonder what the rubber band would sound like when the rubber band is very thin. My prediction is that the thin rubber band would be very high pitched. I also would wonder what the rubber band would sound like when the band is small and tight.
