Introduce some activities that introduce students to the physics of sound. They will also learn how various instruments produce sound. Included are downloadable pdf worksheets and answer sheets to use.

[Free Registration/Login Required] An descriptive text about the sounds a person would hear at a baseball game. A question sheet is available to help students build skills in reading comprehension.

Test your knowledge of sound with this ten-question quiz.

In this interactive demonstration, students will observe while the teacher creates two sound frequencies using open tube resonators of nearly identical length. The nearness in length produces two slightly different frequencies which...

Just how loud does a sound have to be for us to hear it? And how loud is too loud for our ears? Learn to measure levels of sound in this project, and discover the amazing auditory range your ears can detect in the noisy world around you.

Want to start a garage band, but Mom or Dad won't let you because it will make too much noise? This is a good project for someone who is interested in acoustics and likes to build things. The objective of this project is to determine if...

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.

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...

In this module, students investigate the properties and behavior of different types of waves.

[Free Registration/Login may be required to access all resource tools.] Students investigate and analyze characteristics of waves, including velocity, and calculate the relationship between wave speed, frequency, and wavelength.

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...

This simulation is a slow motion version of what you might actually see if you could see particles in a medium vibrating.

The Sound and Light interactive investigates these two forms of energy. Students will enjoy exploring how sound and light are created, travel, and can be controlled.

In this lesson plan students experience a series of demonstrations that show how sound is made and heard. Students will experiment with sound traveling through different mediums and sound that has different pitches.

This list describes common misconceptions children have about sound and the scientific explanation for those ideas.

Learners 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.

A simulation that shows what happens to a sound wave when the pitch is changed.

In this activity, students use a variety of materials to design and create headphones that absorb sound.

Great animations showing how sound is produced.

The Sound and Light unit provides students with an understanding of sound and light waves through the theme of the "Sunken Treasure," a continuous story line throughout the lessons. In Lessons 1-5, students learn about sound, and in...

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...

Review the characteristics of periodic transverse and longitudinal waves such as wavelength, crest, trough, amplitude, expansion, and compression.

Every second billions of waves-sound waves, radio waves, light waves-pass through or bounce off our bodies. Over time people have developed technologies that make use of these natural phenomena to accomplish their goals such as creating...

For this activity, young scholars make a sound cylinder using a cardboard tube, and investigate the sound wave vibrations they can feel at its end when they speak into it.
