By the end of this section, you will be able to define antinode, node, fundamental, overtones, and harmonics; identify instances of sound interference in everyday situations; describe how sound interference occurring inside open and...

By the end of this section, you will be able to define intensity, sound intensity, and sound pressure level and to calculate sound intensity levels in decibels (dB).

Physiclips thoroughly presents the concept of sound with animations and film clips. Learn about the properties of sound and the physics behind sound waves with this site.

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.

Sound the alarm! Fire alarms and fire trucks are perfect examples of communicating with light and sound. Learners will begin to understand the engineering principles behind why fire alarms and fire engines use both light and sound to...

Hosted by Annette Bening, Sounds and Symbols focuses on how children learn the relationship between sounds, letters, and words as an initial step before being able to decode the printed word. Features children's book author and...

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.

Learn about terms to quantify sound like pitch, frequency, decibels, and much more in this learning module. Learning module includes animations and videos.

This four-day professional development session introduces teachers to the OpenSciEd materials generally in addition to the 8.2 Sound Waves unit.

In this unit, 8th graders develop ideas related to how sounds are produced, how they travel through media, and how they affect objects at a distance.

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

Eighth graders develop ideas related to how sounds are produced, how they travel through media, and how they affect objects at a distance.

This page contains audios of sounds for single letters. The audios give the letter sound and then pronounce a word that uses that sound. It gives only the short vowel sounds. The sounds are pronounced in a North American accent.

A comprehensive site on English pronunciation for English language learners and their teachers. It offers explanations and activities for pronunciation of specific sounds, of letter combinations, of word stresses, and of phrasal words....

An excellent resource for teaching beginning letter-sound correspondence. Student must identify the object in the picture and circle the letter that begins the word.

An activity to build students' abilities to identify sounds, even in nonsense words. The teacher says a word and states that it is not a real word, but asks the students to just listen for the sounds.

A small group activity. Each group receives a Graph the Sound page (link included on site). The teacher holds up a picture and the group must graph each sound they hear when they pronounce the word.

Using microphones connected to computers running Audacity software, student teams experiment with machine-generated sounds and their own voices and observe the resulting sound waves on the screen, helping them to understand that sounds...

How can scientists lump heat, light and sound together when investigating properties and behaviors? This learning module will address that question through a series of activities.

In this bingo game, listen for the sounds of the letters and click on the correct letter; when you have completed all the letters, a picture is revealed.

For this investigation, students will observe and experiment with how sounds are made. They will use various elementary music instruments as well as tuning forks, combs, rubber bands, books, bottles, etc. They will collect data on how...

How can you tell if something is making a sound? This lesson will show that to produce sound, an object must vibrate. Included are a minute-by-minute lesson plan, activities, and teacher discussion points and questions.

This interactive Super Why! game features a BINGO game. Students listen to Princess Pea read aloud the following: initial vowel sounds, initial consonant sounds, and/or words with emphasized initial vowel or consonant sounds. Then...

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.
