Showing 10 experiments that use the Wireless Sound Sensor.
Sound of Vibrating Strings
We will explore qualitatively how string tension, length, and linear density affect the sound of the vibrating string. Then we will take measurements for...
Wavelength, Frequency, and Wave Speed in a Guitar String
Students investigate the relationship between string length, wavelength, frequency, period, and wave...
Blockly Extension: Acoustic Stopwatch
Students develop Blockly code that uses data from a Wireless Sound Sensor to trigger start and stop...
Waves and Energy
Students learn that sound is produced by vibrating objects, that sound travels from a source through air, solids, and liquids, and its loudness depends...
Determining Sound Levels
Students learn that sound is produced by vibrating objects, that sound travels from a source through air, solids, and liquids, and its loudness on the...
Decoding DTMF Tones
Students will use a wireless sound sensor and the fast Fourier Transform (FFT) display of the data collection software to analyze the tones produced when...
Measuring the Speed of Sound with an Echo
Students will first predict the speed of sound in the air of their classroom using a simple relationship...
Properties of Sound Waves
Students will learn the meaning of terms (frequency, period, crest, trough, amplitude, wavelength and wave speed) used to describe waves by studying sound...
Blockly Extension: Acoustic Stopwatch
Students develop Blockly code that uses data from a Wireless Sound Sensor to trigger start and stop...
Design a Musical Instrument
Create a musical instrument that plays the frequencies of all 8 notes of a major scale, has working parts consisting of metal bar (or tube) with lengths...
