The Problem: Is there a connection between vibration and sound?
The Hypothesis:
.
The Experiment: Fill several glasses with different amounts of water. Strike each glass gently with a spoon.
Observations: Do the glasses sound the same?
What happens when you place your hand on the glass right after you strike it?
.
What happens when your hand is holding the glass at the same time that you strike it?
.
Interpretation: You can't fully solve this problem from this experiment, but what have you discovered?
.
Conclusion: Is there a connection between vibration and sound?
Can you think of other ways to experiment with sound?
.
For Further Study: Design another experiment with sound. For example, use a guitar, a rubber band, a tuning fork--strike it and place it in a bowl of water or in a "tin can telephone". Bang on a variety of objects!
