This activity enables students to calculate the speed of sound in a laboratory setting.

This activity is an inquiry lesson where students investigate objects and their associated sound due to vibration. Students will write their observation and interpret how and why sound vibrations occurs.

In this introductory physics lab activity, students explore the sounds made by the free-end of a ruler vibrating off the end of a desk.

Learn how to make waves of all different shapes by adding up sines or cosines. Make waves in space and time and measure their wavelengths and periods. See how changing the amplitudes of different harmonics changes the waves. Compare different mathematical expressions for your waves.

This online exhibit explores the history and development of the electric guitar. It includes information about the instrument designers and the musicians who influenced the creation of new guitars and innovations in their sound. Examples of about 40 different guitars are included with descriptions of each. There is also information on how different types of acoustic and electric guitars operate with the sounds of each available for listening. Finally, addition information, references, and links are included.

In this classroom guided inquiry lesson, students will rotate through five stations of various sound instruments to look at how length affects pitch. Student will develop a hypothesis, make observations, and draw a conclusion about what happens when the length of the vibrating sound source changes.

This activity is a classroom experiment where students learn about sound. Students will use musical instruments to explore the relationship between length and pitch.

This activity is a classroom activity where students use the inquiry method to answer the question "How is sound made?" by observing different sound producers and coming up with their own conclusion.

This activity is an experiment on how sound is energy and travels in waves. Students will investigate sound using different objects in the room.

Students will investigate how sounds are made and changed, record their findings in their journal, share these findings with the class, and develop further questions about sound.

This is an activity demonstrating how pitch varies using water bottles, and allows students to investigate pitch further with rulers, straws, and water bottles.

This is a small group kindergarten activity where students determine what film containers sound the same by using their sense of hearing.

How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.

This activity is a classroom lesson on how a slinky relates to sound waves and how sound waves relate to the human ear.

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer. You can vary friction and the strength of gravity. Use the pendulum to find the value of g on planet X. Notice the anharmonic behavior at large amplitude.

This activity is an investigation where students use tools to determine how the length of a sound source affects its pitch.

Broadcast radio waves from KPhET. Wiggle the transmitter electron manually or have it oscillate automatically. Display the field as a curve or vectors. The strip chart shows the electron positions at the transmitter and at the receiver.

This simulation lets you see sound waves. Adjust the frequency or volume and you can see and hear how the wave changes. Move the listener around and hear what she hears.

This inquiry lab activity involves students working to understand that sound is made from vibrations.

This inteactive lecture and series of demonstrations develops the concepts and vocabulary of oscillatory motion as it relates to the motion of a mass on a spring.
