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....

The sound waves of thunder are made when lightning very quickly heats the air surrounding it, expanding faster than the speed of sound. Learners explore waves through their own movement of string or set waves to constantly oscillate....

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...

What can your class tell about a wave just by looking at it? Using a simulation, physics pupils work through a series of case studies to determine the effects of speed, frequency, and density on waves. Part of a larger playlist on waves...

Learners explore the science of sound by considering the characteristics that make unique sounds. Through an interactive simulation, they adjust tension and string size and view the corresponding wavelength and amplitude changes. 

Sometimes it's okay to rock the boat! Science scholars manipulate wave properties using a fun interactive. Part of a larger playlist that dives into waves and sound, the lesson helps users work their way from apprentice to wizard by...

Learn about sound waves, which move vibrations from one place to another through liquids, gases and solids, with this interactive lesson.

An introduction to wave traits and how they affect sound.

A physics course web page that features a Java applet in which visitors can observe the waveform resulting from the interference of two waves. The amplitude and wavelength of the interfering waves can be altered and the outcome observed.

What are ways to describe sound? Using the program downloaded called Sound Grapher and the microphone on the computer, students can investigate the frequency, wavelength, amplitude, and velocity of sound waves. Activity includes detailed...
