Investigation 2 / Part

1Vibration and

Pitch

Vibration and Pitch

• Question: How are high and low sounds made?

• Review voc/ concepts learned so far.

• Voice Activity

• Tongue Depressor Activity: Describe and write about how high and low sounds are made.

• Revisit the Door Fiddle and Tone Generator. Compare and contrast instruments. Describe and write about how high and low sounds are made.

Conclusion: (Content Inquiry Question TG p. 12/Inv. 2)

• Fast vibrations produce high-pitched sounds. Slow vibrations produce low-pitched sounds.

• How fast or slow something is moving is called the frequency of the vibration.

Voc: pitch, frequency, volume
