Tuning Fork Discovery
No need for a knife when a fork will do! Groups of pupils first read about the science of sound, and then experiment with tuning forks. Teams gather information about the pitch and length of their forks and compare them to the pitch and...
Acoustical Society of America
Musical Instruments: Part II
String together how instruments produce sound. Using pieces of string, learners find ways to create sound. They investigate changes to the string and the effect of adding a cup. Finally, pupils experiment by changing the way to create...
Science Friday
Make a Speaker
Make science come in loud and clear. Pupils learn about how a speaker works by building one. The scholars first learn about electromagnetic fields by building an electromagnet. Using that knowledge, they build a crude speaker using a...
Purdue University
Design of Music Instruments for a Rock Band
Can you create a rock band? Scholars learn about the creation and transmission of sound in a hands-on STEM activity. First, they explore the transmission of sound using a tuning fork. Then, they must solve the problem of missing...
Purdue University
Sound Absorption Wall
What types of materials absorb sound? Learners explore sound waves, the decibel scale, and how different materials affect sound. Then, they use their knowledge of sound meters to complete a STEM engineering design task to build...

Pan Flute
How can a pan flute sound one note while we hear a chord? The simulation explores sound waves, vibrations, and harmonics at the molecular level. Scholars control the pipe into which air is being blown, the length of the pipe, and which...
LABScI
Acoustics: The Sound Lab
If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels. Whole...
