How Loud Is Too Loud?
How loud was that? Individuals build wheels displaying different sounds. Then, learners use the wheels to find the number of decibels the sound creates and how long they could withstand the sound before potential hearing damage.

Good Vibrations
Visualize vibrations within the classroom. Pupils see the connection between sound and waves. The learners use a tuning fork in two different ways to demonstrate the waves associated with sound. Scholars see how the sound waves from a...

Wave Basics
Catch the fast wave. Using a computer simulation, pupils experiment with amplitude, frequency, damping, and tension of a string to determine which affects the speed of the wave. Learners record the observations to determine their...

Musical Instruments: Part I
Pupils construct and play various musical instruments made from straws and bottles. They investigate how changes in their instruments result in tone changes. Learners change the lengths and amount of water in the instruments and record...

Doppler Effect
Here comes the sound. After watching a couple videos demonstrating and explaining the Doppler Effect, learners develop their own understanding of the phenomenon. Scholars draw a sound wave and observe how the perception of the wave...

Sound Measures
How loud is the class's hearing threshold? Using a sound level meter, the class members observe how the loudness of sound is affected by distance. Learners continue to study decibels by seeing how different sounds compare to each other...

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...

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...

Musical Instruments
Mix it up and engage learners in a lesson on music and physical science. Using cups, strings, guitars, and voice, the class will experiment with sound vibration and frequency. They'll use each instrument and fill out a worksheet that...

Generalizing How Musical Instruments Work
Sound, vibrations, resonance, and frequency are explored as learners use music to foster scientific inquiry. They engage in three different sound experiments and follow up discussions to foster a better understanding of how musical...

Musical Instruments Part I - Woodwinds
What is the connection between sound and vibration? Learners find out as they conduct a series of experiments with instruments they create. The experiment is well explained, includes modifications for visuall and hearing impaired...

Anatomy of a Wave
Pair physical science learners up, and have one describe a transverse wave while the other blindly attempts to draw it. Then reveal an actual diagram and explain the different parts of the wave: crest, trough, wavelength. Though most of...
