SOUND AROUND ACTIVITIES
This section contains simple activities on sound that can be done in the classroom. First, here are some simple definitions:
- Vibration: the back and forth movement of an object.
- Volume: the loudness or softness of a sound
- Amplification: making the sound louder
- Pitch: the highness or lowness of a sound
- Frequency: the rate of vibration.
(For example, the lowest sound that a person can hear is a frequency of roughly 16 to 20 times per second and the highest sound is at a frequency of about 20,000 times per second, although other animals have different hearing ranges.)
