Experiment 2
Pitch: How does the thickness of a vibrating string affect sound?

Purpose/Hypothesis

In this experiment, you will explore how the thickness of the vibrating object affects the pitches it produces. You will use different sizes of rubber bands to test this effect. Before you begin, make an educated guess about the outcome of this experiment based on your knowledge of sound. The educated guess, or prediction, is your hypothesisAn idea in the form of a statement that can be tested by observation and/or experiment.. A hypothesis should explain these things:

• the topic of the experiment
• the variable you will change
• the variable you will measure
• what you expect to happen

A hypothesis should be brief, specific, and measurable. It must be something...
