Go Direct® Sound Sensor

Speed of Sound

Sound - Production and Propagation

Measure time between clap and echo to calculate speed of sound; directly validates textbook value of 332 m/s

Sound in Different Media

Sound - Production and Propagation

Compare sound intensity through different materials (wood metal air); demonstrates medium requirement for propagation

Vibrating Objects and Sound

Sound - Production and Propagation

Strike tuning fork and measure sound waveform; shows sound is produced by vibrating objects as per textbook

Frequency and Pitch

Reflection and Characteristics of Sound

Measure frequency of tuning forks of different pitches; verify that higher frequency = higher pitch

Amplitude and Loudness

Reflection and Characteristics of Sound

Strike tuning fork softly then harder; measure amplitude difference; shows loudness depends on amplitude
