Serc: Experimenting With Sound/compression Waves Through Vibration

Can you hear it now? Young scientists experiment with sound waves using metal objects and string. They strike metal objects while they hold them and as the objects hang from a string to compare the sound. They discover that sound travels...

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...

Set up a set of colorful liquid-filled bottles that produce sounds when tapped with a spoon. When teaching primary physicists about sound, they can experiment with pitch, comparing it the amount of liquid in the bottle. Which makes a...

Long, rippled, plastic tubes are swung around in circles, making air pass through them, and creating sound waves. This is a simple and inexpensive toy that you can let learners experiment with as they learn about sound and pitch. Go...

In studying the solar system, students compare the relative sizes of the sun and the moon, and experiment with angular diameter, apparent diameter and distance.

In this video segment, adapted from ZOOM, a tuning fork's vibrations are made visible as ripples in a bowl of water. [0:51]

In this video segment adapted from ZOOM, the cast investigates how the pitch of sound changes when they strike a variety of glasses filled with different amounts and types of liquids. [5:07]

An inquiry lesson where students explore pitch and the rate of vibration. Students will look at how the rate of vibration which creates pitch is affected by the size of the object studied.

Students investigate how pitch varies with the length of instrument in this activity. Activity includes procedure and background information.

Listen in as Mia and Sam expound on sound. It is caused by vibrations and travels in waves. It has the qualities of pitch, frequency, and volume. This hip animation displays a graph to depict the frequency and amplitude of sound waves....
