Activity 5.2: Rubber Band Guitar. 1. Stretch different thicknesses of rubber bands around an empty tissue box or the container. 2. Pluck each rubber band. 3. Observe the vibrations and compare the sounds. Write down your conclusion.

Here are the observations and conclusion for Activity 5.2:

Observations:

Objects	Did it vibrate?	Sound produced?
Ruler	Yes	A sound is produced (e.g., a twang).
Thin rubber band	Yes	A high-pitched sound is produced.
Thick rubber band	Yes	A low-pitched sound is produced.

Conclusion:
When objects like a ruler or rubber bands are plucked, they vibrate, and these vibrations produce sound. The characteristics of the sound, such as its pitch, depend on the properties of the vibrating object; for example, thinner rubber bands produce higher-pitched sounds than thicker ones.
