Students examine the existence of sound by listening to and seeing sound waves while conducting a set of simple activities as a class or in pairs at stations. Students describe sound in terms of its pitch, volume and frequency. They use...

Discusses the ear drum receiving vibrations and how the amplitude of those vibrations translates into the loudness of the sound. Good diagrams to illustrate this concept.

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and...

Through animations, videos, and text, students discover that all objects have a natural frequency or set of frequencies at which they vibrate.

Strike a key on the piano, and you hear the string vibrating. Just about any object vibrates when it's knocked, but how much and how fast? This project helps you find out. You'll build a simple light-sensing circuit for measuring the...

Sound! How does it work? All you need to know about it is found here through a series of Q&As. Educators will find useful lesson plans.

Students discover how vibrations produce sound by making this sound sandwich out of everyday materials. Lesson plans include three videos that give an introduction, step-by-step demonstration, and an explanation of the science behind the...

The focus of this physics tutorial is on the application of mathematical relationships and standing wave concepts to musical instruments in three general categories of instruments: instruments with vibrating strings, open-end air column...

With videos, illustrated diagrams, and informational text, students learn about sound waves as forced vibrations.

An experiment that explores the relationship between vibrations and pitch. This site includes web links, a challenge question, and notes to the teacher.

For musical instruments and other objects that vibrate in regular and periodic fashion, the harmonic frequencies are related to each other by simple whole number ratios. Students learn why these whole number ratios exist for a musical...

A guitar string has a number of frequencies at which it will naturally vibrate. These natural frequencies are known as the harmonics of the guitar string. Students work through several example problems.

A physics lesson where students investigate how sound can be produced and changed. Students identify vibrations as the source of sound and how it can be amplified and received, and then explore the use of a slinky to explain the nature...

To further their understanding of sound energy, students identify the different pitches and frequencies created by a vibrating ruler and a straw kazoo. They create high- and low-pitch sound waves.

Music can loosely be defined as organized sound. The lesson objectives, understanding sound is a form of energy, understanding pitch, understanding sound traveling through a medium, and being able to separate music from sound, can...

This document will give you "extra" information and opportunities to build your understanding of sound so that you can be better prepared to facilitate the sound lessons with your students.

Science instruction is most effective when using a hands-on delivery system. This lesson will use your young scholars' natural affinity for music and musical instruments to reinforce and refine their knowledge of the nature of sound -...

A reference page including content and animations on longitudinal waves. Understand how sound waves are produced from vibrations in guitar strings to produce longitudinal waves.

This resource explores how vibrating objects produce sound waves. The site contains information and an animation.

An activity where students investigate the sounds created by the friction of fingers moving along a wet string.

Elaborate on the essential characteristics and the causes of standing wave patterns and relate these patterns to the vibrations of musical instruments.

Illustrated diagrams and interactive practice problems show constructive and destructive interference occurring at sound beats.

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 begin to explore the relationship between the length of an object and the sound it produces as it vibrates, by using a wood or plastic ruler and the edge of a desk or table.
